Expose ccdb.connection_parameters as an optional BOSH property on both cloud_controller_ng and cloud_controller_worker jobs. Operators can use this to configure PostgreSQL session parameters (statement_timeout, idle_in_transaction_session_timeout) and TCP keepalive settings (keepalives, keepalives_idle, keepalives_interval, keepalives_count) from the BOSH manifest instead of requiring DB-level configuration.

There was a problem hiding this comment.
Should we rename the parameter to psql_connection_parameters? To have a clear distinction between PostgreSQL and potentially upcoming MySQL connection parameters.

A short explanation of the proposed change:
Currently CC relies on connection timeouts configured globally at the CCDB level (e.g.
statement_timeout = 1h,idle_in_transaction_session_timeout = 10min). With this feature, these settings are now configurable in the BOSH manifest alongside other Cloud Controller (CC) configuration, without requiring direct database access.Links to any other associated PRs
