Shore up "masking" of secrets in Configuration view

The PSPNG provisioner I guess depends on an LDAP property that ends in bindCredential instead of password, and the Configuration view in the UI of the loader properties doesn't mask it the way it does other property names it thinks are secrets. Seems like an obvious/simple fix. I'm aware that it would be masked if it were stored in the database directly, but that's not always the goal.
