Hammer CLI

Cloned from BZ:

Description of problem:
A VMware type compute resource can have multiple clusters defined within it (defined by VMware). Full use of the `hammer` command for provisioning requires we specify a cluster ID to deploy to. There is no way to currently list the clusters within a compute resource.

Version-Release number of selected component (if applicable):
tfm-rubygem-hammer_cli-0.11.0.1-1.el7sat.noarch

How reproducible:
Always

Steps to Reproduce:
1. Configure a VMware type compute resource within Satellite 6.3
2. Issue `hammer compute resource info --id 1`
3. See no information about clusters within the given compute resource

Actual results:
No information on clusters, no additional commands to list information on clusters in `hammer compute-resource --help`

Expected results:
Either a listing of all clusters or an additional command sequence to get that list.
