Edit Mirror: Table Removal

[Amogh-Bharadwaj]

Table picker in Edit Mirror page now allows selection and deselection of all tables.

Table removal now consists of:

1. Removing the table from the publication if PeerDB created it
2. Removing the table from the raw table - if applicable to the destination connector (Postgres, BigQuery, Snowflake, Clickhouse)
3. Update table mappings in our states

Notes:

• Changing target table name of existing tables is disallowed
• Deselecting columns of existing tables in the mirror is currently disallowed

Functionally tested with table removal and table addition of the same table for PG to Clickhouse

TODO:

• [x] Write a couple of e2e tests for the four warehouse connectors
• [x] Functionally test for PG, SF and BQ
