This PR lays most of the groundwork required for emitting events when
features are marked as potentially stale by Unleash. It does **not**
emit any events just yet. The summary is:
- periodically look for features that are potentially stale and mark
them (set to run every 10 seconds for now; can be changed)
- when features are updated, if the update data contains changes to the
feature's type or createdAt date, also update the potentially stale
status.
It is currently about 220 lines of tests and about 100 lines of
application code (primarily db migration and two new methods on the
IFeatureToggleStore interface).
The reason I wanted to put this into a single PR (instead of just the db
migration, then just the potentially stale marking, then the update
logic) is:
If users get the db migration first, but not the rest of the update
logic until the events are fired, then they could get a bunch of new
events for features that should have been marked as potentially stale
several days/weeks/months ago. That seemed undesirable to me, so I
decided to bunch those changes together. Of course, I'd be happy to
break it into smaller parts.
## Rules
A toggle will be marked as potentially stale iff:
- it is not already stale
- its createdAt date is older than its feature type's expected lifetime
would dictate
## Migration
The migration adds a new `potentially_stale` column to the features
table and sets this to true for any toggles that have exceeded their
expected lifetime and that have not already been marked as `stale`.
## Discussion
### The `currentTime` parameter of `markPotentiallyStaleFeatures`
The `markPotentiallyStaleFetaures` method takes an optional
`currentTime` parameter. This was added to make it easier to test (so
you can test "into the future"), but it's not used in the application.
We can rewrite the tests to instead update feature toggles manually, but
that wouldn't test the actual marking method. Happy to discuss.
This PR takes the project status API a step further by adding the
capability of providing a date to control the selection. We are
currently making calculations based on a gliding 30 day window, updated
once a day. The initial database structure and method for updating the
UI is outlined in this PR.
## About the changes
Variants are now stored in each environment rather than in the feature
toggle. This enables RBAC, suggest changes, etc to also apply to
variants.
Relates to [roadmap](https://github.com/orgs/Unleash/projects/10) item:
#2254
### Important files
- **src/lib/db/feature-strategy-store.ts** a complex query was moved to
a view named `features_view`
- **src/lib/services/state-service.ts** export version number increased
due to the new format
## Discussion points
We're keeping the old column as a safeguard to be able to go back

* feat: add impression data column
* fix: add default value to impressionData
* fix: allow client api to return impressionData
* fix: add tests for impressionData
* fix: reset server-dev
* fix: add test for adding a toggle with impression data on a different project
* fix: update tests
This triggers when we update or overwrite variants, and will include the
previous variants and the new variants.

Add a new .../:feature/variants API
This adds
- `GET /api/admin/projects/:projectId/features/:featureName/variants` which returns
```json
{ version: '1', variants: IVariant[] }
```
- `PATCH /api/admin/projects/:projectId/features/:featureName/variants` which accepts a json patch set and updates the feature's variants field and then returns
```json
{ version: '1', variants: IVariant[] }
```
- `PUT /api/admin/projects/:projectId/features/:featureName/variants`
which accepts a IVariant[] and overwrites the current variants list for the feature defined in :featureName and returns
```json
{ version: '1', variants: IVariant[] }
- This also makes sure the total weight of all variants is == 1000
- Validates that there is at least 1 'variable' variant if there are variants
- Validates that 'fix' variants total weight can't exceed 1000
- Adds tests for all these invariants.

Adds environment support
This PR adds environments as a first-class concept in Unleash.
It necessitated a full rewrite on how we connect feature <-> strategy, as well as a rethink on which levels environments makes sense.
This enables PUTs on strategy configurations for a feature, since all strategies now have ids.
This also updates export/import format. The importer handles both formats, but export is no longer possible in version 1 of the export format, only in version 2, with strategy configurations for a feature as a separate object.
