cloudmonkey: misses a couple of verbs for 'lock' and 'disassociate'

The following api commands have no cloudmonkey equivalent because
cloudmonkey grammar misses the related verbs.

~/tools/cli/cloudmonkey/marvin/cloudstackAPI(branch:master*) $ ls disassociateIpAddress.py
disassociateIpAddress.py

------------------------------------------------------------
~/tools/cli/cloudmonkey/marvin/cloudstackAPI(branch:master*) $ ls lock*
lockAccount.py lockUser.py
------------------------------------------------------------
