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

* chore: remove unused test helper from sqlstore
TimeNow() is no longer used in any tests in this package.
* chore: move sqlstore.SQLBuilder to the infra/db package
This required some minor refactoring; we need to be a little more explicit about passing around the dialect and engine. On the other hand, that's a few fewer uses of the `dialect` global constant!
* chore: move UserDeletions into the only package using it
* cleanup around moving sqlbuilder
* remove dialect and sqlog global vars
* rename userDeletions to serviceAccountDeletions
* chore: add alias for InitTestDB and Session
Adds an alias for the sqlstore InitTestDB and Session, and updates tests using these to reduce dependencies on the sqlstore.Store.
* next pass of removing sqlstore imports
* last little bit
* remove mockstore where possible
