Implement tables.list and tables.delete RPC APIs on the schema page

[seancolsen]

This PR implements the following RPC methods on the schema page, making it possible to list tables, delete tables, and patch tables.

Endpoint	HTTP Method	Function
/api/db/v0/tables/	GET	tables.list
/api/db/v0/tables/{tableId}/	DELETE	tables.delete
/api/db/v0/tables/{tableId}/	PATCH	tables.patch

I'll handle creating tables in a separate PR.

@seancolsen I scanned through the code and it looks fine.

However, I'm not able to get tables to list on the UI while testing.

Screenshot:

Request:

{
  "jsonrpc":"2.0",
  "id":0,
  "method":"tables.list_with_metadata",
  "params": {
    "database_id":1,
    "schema_oid":2200
  }
}

Response:

{
    "id": 0,
    "jsonrpc": "2.0",
    "error": {
        "code": -31049,
        "message": "TypeError: 'NoneType' object is not iterable"
    }
}

I assume this is because I do not have any metadata and somewhere in the backend it's trying to read and merge a non-existent metadata.

[seancolsen]

@pavish as far as I can tell, this is a backend bug. I've opened #3702 to fix it.

Can you re-test with a schema that contains tables?

I've tested with a schema that has tables, both with and without metadata, and it seems to work.

@seancolsen Looks good to me!

As discussed over call, we could merge this PR after resolving the conflicts here once #3710 is merged.
