Currently foreman only returns a arrray of hostnames as the default index action for json output.

I would like to add more host attributes so I don't have to make more calls to foreman in future requests.

This will break versions of remoteadmin prior to upcoming 0.6 version and may cause issues with foreman CLI but I think its a better solution in the long run.

I am adding the following attributes:

id, hostgroup_id, puppet_status.

It will be easy to add more attributes later.
