Hammer CLI

Compared to the web UI command hostgroup info lacks following fields:

Hostgroup
  Parent (we currently show only Parent ID)
  rename Environment to Puppet environment?
  Compute profile
  Puppet master (we currently show only ID)
  Puppet ca (we currently show only ID)
Network
  Subnet ipv4
  Subnet ipv6
  Realm
Operating system
  Media Selection
  PXE Loader
  Activation keys

I think it would be good idea to structure the output according to UI tabs, to make it better arranged.

Host info lacks some fields too:

Host
  Puppet master (we currently show only ID)
  Puppet ca (we currently show only ID)
Network
  Subnet ipv4 (rename from "Subnet")
  Subnet ipv6
  IPv4 address (rename from "IP address")
  IPv6 address
Operating system
  PXE Loader
