Kirill Bulatov ec3a3aed37 Dump current tenant config (#3534) ...

The PR adds an endpoint to show tenant's current config: `GET
/v1/tenant/:tenant_id/config`

Tenant's config consists of two parts: tenant overrides (could be
changed via other management API requests) and the default part,
substituting all missing overrides (constant, hardcoded in pageserver).
The API returns the custom overrides and the final tenant config, after
applying all the defaults.

Along the way, it had to fix two things in the config:

* allow to shorten the json version and omit all `null`'s (same as toml
serializer behaves by default), and to understand such shortened format
when deserialized. A unit test is added
* fix a bug, when `PUT /v1/tenant/config` endpoint rewritten the local
file with what had came in the request, but updating (not rewriting the
old values) the in-memory state instead.
That got uncovered during adjusting the e2e test and fixed to do the
replacement everywhere, otherwise there's no way to revert existing
overrides. Fixes #3471 (commit
dc688affe8)
* fixes https://github.com/neondatabase/neon/issues/3472 by reordering
the config saving operations
