Use usual __name__ idiom for monitoring DB manager logging (#3921)

Since PR #3817, the database manager has been started using
multiprocessing spawn, rather than fork, as part of issue #3723, and
since then, this special logger naming has been unnecessary.

See PR #3644 for the same change on the htex interchange, including more
detailed explanation/justification.


# Changed Behaviour

This PR probably doesn't change which log lines are logged now. It does
open up the opportunity for Parsl helper functions to log things into
the database manager log now. And log lines are now longer, because
their topic is now "parsl.monitoring.db_manager", not
"database_manager".
