## About the changes
Introduce a snapshot version of instanceStats inside
instance-stats-service to provide a cached state of the statistics
without compromising the DB.
### Important notes
Some rule-of-thumb applied in the PR that can be changed:
1. The snapshot refresh time
2. The threshold to report appName with the metrics
## Discussion points
1. The snapshot could be limited to just the information needed (things
like `hasOIDC` don't change until there's a restart), to optimize the memory usage
3. metrics.ts (used to expose Prometheus metrics) has a [refresh
interval of
2hs](2d16730cc2/src/lib/metrics.ts (L189-L195)),
but with this implementation, we could remove that background task and
rely on the snapshot
4. We could additionally update the snapshot every time someone queries
the DB to fetch stats (`getStats()` method), but it may increase
complexity without a significant benefit

## About the changes
This is a follow-up on #1953
This implementation generalizes how we fetch some standard parameters
from the query parameters or request body.
## Discussion points
Unfortunately, we have not used standard names for our APIs and one
example is our `projectId` (in some cases we just used `project`).
Ideally, we're only using one way of sending these parameters either
`projectId` or `project` (same applies to `environment` vs
`environmentId`).
If both parameters are present, due to historical reasons, we'll give
precedence to:
- `projectId` over `project`
- `environment` over `environmentId`
In the presence of both query parameters and body, we'll give precedence
to query parameters also for historical reasons.

This PR fixes the admin feature schema by moving the `strategies`
(featureStrategySchema) from the root of `feature` object to
`feature.environment`

## About the changes
This uses log-level warning so we can turn off the log without turning
off all error logs. This could potentially be tweaked further by using
log categories in the log configuration.
Closes#2057
## About the changes
According to our docs, we only support up to 1 decimal place for
weights. This is to use integers to represent the percentages (we divide
them by 10) and supporting more decimals results in bad maths due to
floating point arithmetics.
This PRs adds Frontend and Backend validations to enforce this
restriction
Closes#2222
## Discussion points
Should we reconsider supporting more decimal places, that door remains
open, but for now we'll just adhere to our documentation because that
change would require some development.
## About the changes
When exporting features one is normally also interested in disabled
features, so they are also included in the export file, while the
variants are not. I do not see a good reason for that, so this PR
removes the check and exports the variants then as well.
I could also add an option as well, but as long as there is no good
reason for ignoring the variants I would just export them with the
features.
This PR adds tests on #2719Closes#2719

We have experienced side-effects where the import was unexpected and
resulted in environments thought to be removed. This had the unexpected
side-effect of also deleting API keys for some environments not part of
the import file.
This commit removes the ability of the state-service to mutate api keys
directly. There is no compelling reasons why we should remove API keys
as part of an import query.

## About the changes
To avoid showing too much data in the traffic screen, limit the number
of results to `topk`.
## Discussion points
Top 10 is a rule of thumb, but maybe we could do top 25. Until we gather
more data, I believe this should be good enough
## What
Previously when importing strategies we've used the same data type we've
used for creating strategies (the minimal, a name, an optional
description, optional parameters and an optional editable column). This
meant that exporting strategies and then importing them would reactivate
deprecated strategies. This PR changes to allow the import to preserve
all the data coming in the export file.
## Tests
Added four new tests, two new unit tests using our fake stores and two
new e2e tests. Interestingly the ones in the fake store ran green before
this change as well, probably because we just insert the parsed json
object in the fake store, whereas the real store actually converts the
object from camelCasing to the postgresql snake_casing standard.
## Discussion points:
### Mismatch between fake and real stores
This is inevitable since storing things in javascript arrays vs saving
in a real database will have some differences, but this again shows the
value of our e2e tests.
### Invariants
Should we see if we can add some invariants to our import/export so that
we can write some proptests for it? One candidate is commutativity of
import/export. On a fresh database importing and then exporting should
yield the same file that was imported provided all flags are turned on.
Candidate for Q1 improvement of import/export.
Adding stricter types to `FlagResolver` can possibly help improve our DX
- Help us prevent errors like typos, guide us to correctly add a flag
when needed, and warn us of stray checks whenever we do a clean up at a
later stage.
## About the changes
This PR improves our queries to Prometheus (instead of making multiple queries do only one) and improves the UI and the code.
The reports aggregate all HTTP methods (GET, POST, PUT, DELETE, OPTIONS, HEAD and PATCH) without distinction under the same "endpoint" (a relative path inside unleash up to a certain depth)

## About the changes
This metric will expose an aggregated view of how many client
applications are registered in Unleash. Since applications are ephemeral
we are exposing this metric in different time windows based on when the
application was last seen.
The caveat is that we issue a database query for each new range we want
to add. Hopefully, this should not be a problem because:
a) the amount of ranges we'd expose is small and unlikely to grow
b) this is currently updated at startup time and even if we update it on
a scheduled basis the refresh rate will be rather sparse
## Sample data
This is how metrics will look like
```
# HELP client_apps_total Number of registered client apps aggregated by range by last seen
# TYPE client_apps_total gauge
client_apps_total{range="allTime"} 3
client_apps_total{range="30d"} 3
client_apps_total{range="7d"} 2
```
## About the changes
The deprecated /api/admin/features endpoint supported querying with tag
and namePrefix parameters.
This PR adds this functionality to
/api/admin/projects/<project>/features as well, allowing to replicate
queries that used to work.
Closes#2306

## Discussion points
I'm extending our query parameters support for
/api/admin/projects/<projectId>/features endpoint. This will be
reflected in our open-api spec, so I also made an
adminFeaturesQuerySchema for this.
Also, very open for something similar to what we did for the modifyQuery
for the archived parameter, but couldn't come up with a good way to
support subselects using the query builder, it just ended up blowing the
stack. If anyone has a suggestion, I'm all ears.

## What
We've already added the backend for this. This is the initial work for
drawing a chart for instance traffic in the frontend. It requires the environment variable `PROMETHEUS_API` set to a valid prometheus-query-language (promql) supported backend, such as Prometheus itself or Victoria Metrics. Besides, at the moment we're hiding this functionality behind the flag `UNLEASH_EXPERIMENTAL_NETWORK_VIEW` which has to be set to true

In this PR we remove the general SettingService cache, as it will not
work across multiple horizontal unleash instances, events are not
published across.
We also fix the CORS origin to:
- Access-Control-Allow-Origin set to "*" if no Origin is configured
- Access-Control-Allow-Origin set to "*" if any Origin is configured to
"*"
- - Access-Control-Allow-Origin set to array and have the "cors"
middleware to return an exact match on the user provided Origin.

## About the changes
This connects our backend with Prometheus (or compatible) metrics
service, and exposes raw data (i.e. acting as a proxy)

Is protected behind a config option called `enableHeapSnapshotEnpoint`.
When API endpoint is triggered it will write a heapSnapshot to disk.
Steps to create heap snapshot:
1. Add env variable `ENABLE_HEAP_SNAPSHOT_ENPOINT=true`.
2. Call this endpoint: `/internal-backstage/heapSnapshot`
3. Download the created heapdump from the server.
The snapshot can be loaded in the chrome dev-tool to analysis.
