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