Joonas Koivunen cb83495744 try: startup speedup (#4366)
Startup can take a long time. We suspect it's the initial logical size
calculations. Long term solution is to not block the tokio executors but
do most of I/O in spawn_blocking.

See: #4025, #4183

Short-term solution to above:

- Delay global background tasks until initial tenant loads complete
- Just limit how many init logical size calculations can we have at the
same time to `cores / 2`

This PR is for trying in staging.
