Groups of hosts.

Manage groups of hosts. This is useful for applying access control to a
number of hosts by using Host-based Access Control.

EXAMPLES:

 Add a new host group:
   ipa hostgroup-add --desc="Baltimore hosts" baltimore

 Add another new host group:
   ipa hostgroup-add --desc="Maryland hosts" maryland

 Add members to the hostgroup (using Bash brace expansion):
   ipa hostgroup-add-member --hosts={box1,box2,box3} baltimore

 Add a hostgroup as a member of another hostgroup:
   ipa hostgroup-add-member --hostgroups=baltimore maryland

 Remove a host from the hostgroup:
   ipa hostgroup-remove-member --hosts=box2 baltimore

 Display a host group:
   ipa hostgroup-show baltimore

 Delete a hostgroup:
   ipa hostgroup-del baltimore
