Add 'openshift_version.py' module

With growth of amount of test cases and supported OpenShift versions we
need to perform more and more version comparisons.
So, this module is designed to ease such operations.

Usage example:

    from cnslibs.common import openshift_version
    version = openshift_version.get_openshift_version()
    if '3.9' < version <= '3.11':
        # Do stuff for OpenShift 3.11 or 3.10
    elif version <= '3.9':
        # Do stuff for OpenShift 3.9 or lower
    else:
        # Do stuff for higher versions than 3.11

Also, reuse it in all the existing places with version comparisons.
