The API should document the compute_profile_id parameter on the hostgroups controller to allow association of compute profiles to host groups.

• associate compute profiles to existing host groups;
• update compute profiles that are associated to existing host groups;

The use case is: as an automator, I'd like to use hammer to create a host group and then associate compute profiles with distinctive configurations for each profile. For instance, if I associate a "1-small" profile to my host group, I then would like to specify the disk size and network device to be used whenever I provision a new host using this host group with the "1-small" profile.
