Description of problem:
There is no (obvious?) way how to configure user data support for OpenStack image via hammer

Version-Release number of selected component (if applicable):
Satellite-6.1.0-RHEL-6-20150721.7-Satellite-x86_64

How reproducible:
always

Steps to Reproduce:
1. Configure OpenStack compute resource
2. Infrastructure -> Compute resources -> <your_cr> -> Images -> [New Image]
(or edit existing one)
Note that there is a "User data" checkbox
3. Now check hammer command for this functionality:

1. hammer --username 'admin' --password 'changeme' compute-resource image create -h
   Usage:
   hammer compute-resource image create [OPTIONS]

Options:
--architecture ARCHITECTURE_NAME Architecture name
--architecture-id ARCHITECTURE_ID
--compute-resource COMPUTE_RESOURCE_NAME Compute resource name
--compute-resource-id COMPUTE_RESOURCE_ID
--name NAME
--operatingsystem OPERATINGSYSTEM_TITLE Operating system title
--operatingsystem-id OPERATINGSYSTEM_ID
--username USERNAME
--uuid UUID
-h, --help print help

1. hammer --username 'admin' --password 'changeme' compute-resource image update -h
   Usage:
   hammer compute-resource image update [OPTIONS]

Options:
--architecture ARCHITECTURE_NAME Architecture name
--architecture-id ARCHITECTURE_ID
--compute-resource COMPUTE_RESOURCE_NAME Compute resource name
--compute-resource-id COMPUTE_RESOURCE_ID
--id ID
--name NAME Name to search by
--new-name NEW_NAME
--operatingsystem OPERATINGSYSTEM_TITLE Operating system title
--operatingsystem-id OPERATINGSYSTEM_ID
--username USERNAME
--uuid UUID
-h, --help print help

Actual results:
There is no way how to configure user data support

Expected results:
There should be a way
