The crmsh package available in kinetic fails to put a cluster node in
maintenance mode, this is part of the scaleback process, more details on
the failure available at the related bug.
This change introduces a new decorator skipVersion() that allows to
provide a list of package versions with an operation flag on how dpkg
should compare the version(s).
The test HaclusterTest.test_930_scaleback() is disabled when running
crmsh-4.4.0-1ubuntu1, at the moment this would be kinetic, although if
any new package gets released this test will be re-enabled automatically
allowing us catch early if the test got fixed or not.
