John Spray 57ae9cd07f pageserver: add flush_ms and document /location_config API (#5860) ...

- During migration of tenants, it is useful for callers to
`/location_conf` to flush a tenant's layers while transitioning to
AttachedStale: this optimization reduces the redundant WAL replay work
that the tenant's new attached pageserver will have to do. Test coverage
for this will come as part of the larger tests for live migration in
#5745 #5842
- Flushing is controlled with `flush_ms` query parameter: it is the
caller's job to decide how long they want to wait for a flush to
complete. If flush is not complete within the time limit, the pageserver
proceeds to succeed anyway: flushing is only an optimization.
- Add swagger definitions for all this: the location_config API is the
primary interface for driving tenant migration as described in
docs/rfcs/028-pageserver-migration.md, and will eventually replace the
various /attach /detach /load /ignore APIs.
