#### Description <!-- Describe your changes in detail --> This PR aims to update some warning levels used in `db_cluster` module to prevent silent failures.

When `db_cluster` tries to do some action in a `db_connector`, it should log some kind of warning (with `conid` that failed) or error instead of debug. When iterating on db_connectors and one fails, it will log a warning with `conid` and if all of the available db are not available it will log an error indicating failure.
