## About the changes
Edit application under
https://app.unleash-hosted.com/demo/applications/test-app is currently
not working as the appName is expected to come in the request body, but
it's actually part of the url. We have two options here:
1. We change the UI to adapt to the expectations of the request by
adding appName to the request body (and eventually removing appName from
the URL, which would be a breaking change)
2. We remove the restriction of only sending the appName in the body and
take the one that comes in the URL. We have a validation that verifies
that at least one of the two sets the appName
([here](e376088668/src/lib/services/client-metrics/instance-service.ts (L208))
we validate using [this
schema](e376088668/src/lib/services/client-metrics/schema.ts (L55-L70)))
In terms of REST API, we can assume that the appName will be present in
the resource `/api/admin/metrics/applications` (an endpoint we don't
have), but when we're updating an application we should refer to that
application by its URL: `/api/admin/metrics/applications/<appName>` and
the presence of an appName in the body might indicate that we're trying
to change the name of the application (something we currently not
support)
Based on the above, I believe going with the second option is best, as
it adheres to REST principles and does not require a breaking change.
Despite that, we only support updating applications as the creation is
done from metrics ingestion
Fixes: #3580
## 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 connects our backend with Prometheus (or compatible) metrics
service, and exposes raw data (i.e. acting as a proxy)
