Fetch DB Query Results

Within Playbooks, different types of databases can be queried. Databases currently supported:

1. ClickhouseDB: Fetch data from your ClickhouseDB.
2. Querying data from PostgreSQL
3. Querying data from an SQL Database which can be authenticated using JDBC-compatible connection string

Note: Any non-bounded query has an auto-limit of 2000 rows added to it in DB query.
