[Ryan J Ollos]

The md5 class that is imported from the hashlib module does not have a new method. Rather, we need to implement the import compatibility similar to how the AccountManagerPlugin has done it: accountmanagerplugin/trunk/acct_mgr/hashlib_compat.py@11864​.

(In [12091]) Refs #10402: Support use of md5 class from the hashlib module or deprecated md5 module, with preference to the former when available.
