Create query to list available tables in a remote server

[FelixMalfait]

Context

Once we have completed #3922 and the user is able to connect a server, the next step is to be able to let them view the tables that they will be able to import.

Implementation

We should create a query remoteServerTables.

From ChatGPT, here's the query to retrieve all the available tables for a given server

SELECT ft.table_name, fs.foreign_server_name
FROM information_schema.foreign_tables AS ft
JOIN pg_foreign_server AS fs ON ft.foreign_server_catalog = fs.srvname
WHERE fs.srvname = 'your_foreign_server_name';
