[discover] S3 data connection (#7917)

Update the S3 type config.

This commit does:
    Browsing connections, databases, tables
    Creating a dataset from a table and setting the string correctly.

This commit does NOT:
    Cache data structures
    Use session ID for querying
    Re-add async polling to search interceptor
