Dont include plugin definition in cmd checks
Dont include plugin definition in cmd checks

The ep for the openstack.cli.extension plugin definition
was being included in the command dict:
'orchestration': ['heatclient.osc.plugin']
Since this is not a command, should be pruned.
This was causing false positives in the overlap checking.
