Replace with '*' password letters for media type in audit log

Issue:

Passwords for media are present as clear text in the audit log (UI) as well as the DB table for auditlog_details.

Occurrence:
This appears to occur when an event is triggered and notifications are sent.

Expected:
The expectation is that the passwords are hashed upon entry for configuring media, and if required in the audit log, the hash/or asterisks are presented. No passwords should be in clear text in the audit log.
