A wrapper for hashlib.md5() has been added to allow OpenStack to run on systems where FIPS is enabled. Under FIPS, md5 is disabled and calls to hashlib.md5() will fail. In most cases in OpenStack, though, md5 is not used within a security context.
In https://bugs.python.org/issue9216, a proposal has been made to allow the addition of a keyword parameter usedforsecurity, which can be used to designate non-security context uses. In this case, md5() operations would be permitted. This feature is expected to be delivered in python 3.9.
Downstream python already supports this option, though. This wrapper simply allows for this option to be supported where the underlying python version supports it.
