Fixes: Python SyntaxWarnings about invalid escape sequences
    
    Otherwise we get some SyntaxWarnings about invalid escape sequences
    such as '\d' and '\{', e.g.:
      /usr/sbin/ipa-replica-manage:393: SyntaxWarning: invalid escape sequence '\{'
        data = re.match('\{replica (\d+) (ldap://.*:\d+)\}(\s+\w+\s+\w*){0,1}', ruv)
      /usr/sbin/ipa-replica-manage:721: SyntaxWarning: invalid escape sequence '\d'
        (re.sub(':\d+', '', x), y)
      /usr/sbin/ipa-replica-manage:726: SyntaxWarning: invalid escape sequence '\d'
        (re.sub(':\d+', '', x), y)
