and add /metrics endpoint to compute_ctl to expose such metrics
metric format example for extension pg_rag
with versions 1.2.3 and 1.4.2
installed in 3 and 1 databases respectively:
neon_extensions_installed{extension="pg_rag", version="1.2.3"} = 3
neon_extensions_installed{extension="pg_rag", version="1.4.2"} = 1

Adds endpoint to install extensions:
**POST** `/extensions`
```
{"extension":"pg_sessions_jwt","database":"neondb","version":"1.0.0"}
```
Will be used by `local-proxy`.
Example, for the JWT authentication to work the database needs to have
the pg_session_jwt extension and also to enable JWT to work in RLS
policies.

This PR introduces a `/grants` endpoint which allows setting specific
`privileges` to certain `role` for a certain `schema`.
Related to #9344
Together these endpoints will be used to configure JWT extension and set
correct usage to its schema to specific roles that will need them.

Add /installed_extensions endpoint to collect
statistics about extension usage.
It returns a list of installed extensions in the format:
```json
{
"extensions": [
{
"extname": "extension_name",
"versions": ["1.0", "1.1"],
"n_databases": 5,
}
]
}
```

## Problem
There are two cloud's features that require extra compute endpoints.
1. We are running pg_dump to get DB schemas. Currently, we are using a
special service for this. But it would be great to execute pg_dump in an
isolated environment. And we already have such an environment, it's our
compute! And likely enough pg_dump already exists there too! (see
https://github.com/neondatabase/cloud/issues/11644#issuecomment-2084617832)
2. We need to have a way to get databases and roles from compute after
time travel (see https://github.com/neondatabase/cloud/issues/12109)
## Summary of changes
It adds two API endpoints to compute_ctl HTTP API that target both of
the aforementioned cases.
