John Spray ea5a97e7b4 pageserver: implement emergency mode for operating without control plane (#5469) ...

## Problem

Pageservers with `control_plane_api` configured require a control plane
to start up: in an incident this might be a problem.

## Summary of changes

Note to reviewers: most of the code churn in mgr.rs is the refactor
commit that enables the later emergency mode commit: you may want to
review commits separately.

- Add `control_plane_emergency_mode` configuration property
- Refactor init_tenant_mgr to separate loading configurations from the
main loop where we construct Tenant, so that the generations fetch can
peek at the configs in emergency mode.
- During startup, in emergency mode, attach any tenants that were
attached on their last run, using the same generation number.
