This adds a version of the SQLStore that includes a ReadReplica. The primary DB can be accessed directly - from the caller's standpoint, there is no difference between the SQLStore and ReplStore unless they wish to explicitly call the ReadReplica() and use that for the DB sessions.
Currently only the stats service GetSystemStats and GetAdminStats are using the ReadReplica(); if it's misconfigured or if the databaseReadReplica feature flag is not turned on, it will fall back to the usual (SQLStore) behavior.
Testing requires a database and read replica - the replication should already be configured. I have been testing this locally with a docker mysql setup (https://medium.com/@vbabak/docker-mysql-master-slave-replication-setup-2ff553fceef2) and the following config:
[feature_toggles]
databaseReadReplica = true
[database]
type = mysql
name = grafana
user = grafana
password = password
host = 127.0.0.1:3306
[database_replica]
type = mysql
name = grafana
user = grafana
password = password
host = 127.0.0.1:3307
* moving folders to slog

* use store cfg, it has side-effects
* fix mutated cfg in tests
Adds support for logs (specify level), metrics (enable metrics and Prometheus /metrics endpoint
and traces (jaeger or otlp) for standalone API server. This will allow any grafana core service
part of standalone apiserver to use logging, metrics and traces as normal.
* separate context and threads for usage stats
* use constants
* ignore original context
* fix runMetricsFunc
* fix collector registration
