docs: Create an internal group. An internal group will always be attached
          to the default (and only) InternalUserDomain within the SMC.
          
          Example of creating an internal user group::
          
              InternalUserGroup.create(name='foogroup2', comment='mycomment')
      
          :param str name: Name of group
          :param list(InternalUser) member: list of internal users to add to
              this group
          :param str comment: optional comment
          :raises CreateElementFailed: failed to create user group
          :rtype: InternalUserGroup
