Karsten Jeschkies 3d5a3936d1 Support limits in multi-tenant queries. (#5626) ... **What this PR does / why we need it**: This changes adds support for the the following limits in multi-tenant queries: - `MaxQuerySeries` - `QuerySplitDuration` - `MaxEntriesLimitPerQuery` - `MinShardingLookback` - `MaxQueryLength` - `MaxQueryParallelism` - `MaxQueriersPerUser` - `MaxCacheFreshness` It always uses the more restricted limit. That means the smallest `MaxQuerySeries` but biggest `QuerySplitDuration`. The split duration is special. Zero means disabled. Also, the global default resolver is the multi tenant resolver when multi-tenant queries are enabled. This will result HTTP 400 errors in case the user sends multiple tenants to endpoints that do not support it. **Which issue(s) this PR fixes**: **Special notes for your reviewer**: **Checklist** - [ ] Documentation added - [x] Tests updated - [x] Add an entry in the `CHANGELOG.md` about the changes.
