Need to be able to set the overcloud name either via template or command line in order to customize hostnames. Currently it is hardcoded to be "overcloud".


This looks like a cross component rfe. It looks like at least these locations are hardcoded for overcloud. 
 

/usr/lib/python2.7/site-packages/rdomanager_oscplugin/v1/overcloud_deploy.py:409:        stack_name = "overcloud"
/usr/lib/python2.7/site-packages/rdomanager_oscplugin/v1/overcloud_deploy.py:438:            orchestration_client, "overcloud")
/usr/lib/python2.7/site-packages/rdomanager_oscplugin/v1/overcloud_deploy.py:587:            'OS_CLOUDNAME': 'overcloud',

Changing these and it appears the install succeeds up until cloud init finishes and puppet starts. So likely there is something in puppet templates that needs to be changed.
