Hammer CLI

Cloned from https://bugzilla.redhat.com/show_bug.cgi?id=1387653
Description of problem:

1. hammer compute-resource image available -h
   Usage:
   hammer compute-resource image available [OPTIONS]

Options:
  --compute-resource NAME        
  --compute-resource-id ID       
  --id ID                        
  --name NAME                   Compute resource name
  -h, --help                    print help

Apparently, the --compute-resource-id option is the same as --id, but hammer requires both:

1. hammer compute-resource image available --compute-resource-id 7
   Missing arguments for 'id'
2. hammer compute-resource image available --id 7
   Error: At least one of options --compute-resource-id, --compute-resource is required
3. hammer compute-resource image available --compute-resource-id 7 --id 7
   -----|-----
   NAME | UUID
   -----|-----

The same goes for names:

1. hammer compute-resource image available --compute-resource local_libvirt
   Missing arguments for 'id'
2. hammer compute-resource image available --name local_libvirt
   Error: At least one of options --compute-resource-id, --compute-resource is required
3. hammer compute-resource image available --compute-resource local_libvirt --name local_libvirt
   -----|-----
   NAME | UUID
   -----|-----

Expected results:

Redundant options should be removed, "hammer compute-resource image available" should require the cr id or name just once.
