Unified Storage: Init at startup, fix traces, and speed up indexing (#97529)

Browse Source 
* dont lazy init unified storage

* Inits index when creating new resource server. Fixes trace propagation by passing span ctx. Update some logging.

* Use finer grained cache locking when building indexes to speed things up. Locking the whole function was slowing things down.

* formatting

* linter fix

* go mod

* make update-workspace

* fix workspaces check error

* update dependency owner in mod file

* wait 1 second before querying metrics

* try with big timeout, see if fixes CI. Wont fail locally.

* skips postgres integration test. Only fails in drone. Will fix later.

* put delay back to 500 ms
