When unified storage is using the grafana db (default case for on-prem), if the db is using ssl then set tls=preferred. This fixes an on-prem bug in 11.3.1.
* Reuse MySQL and Postgres Grafana config instead of the object
- Only reuse the Grafana DB object for SQLite. Support for SQLite will be added in a different PR
- Fail when reusing the Grafana DB object if it is using DB instrumentation
- In the case that we have to reuse a Grafana DB with its instrumentation, fail with an error that describes a workaround
- Add regression tests to reproduce incident 2144
