What this PR does:

Add active query tracker to query frontend with -frontend.active-query-tracker-dir configuration. The tracker logs during startup any previous inflight queries in the case of sudden crash.

This also introduces -frontend.max-concurrent configuration for max concurrency in query frontend.
