The root_pass parameter needs documenting for host groups in the API.

When you create a host group and associate it with an operating system, it is often useful to set the password (root) so that when you provision a system associated to this host group, you know what password to use when trying to ssh into the system. Currently one cannot use hammer hostgroup command to do that.

I'd like to request an improvement to hammer hostgroup so that one can set/update the password field. Perhaps something like:

hammer hostgroup update --name=<name of existing host group> --password=<new value>

or

hammer hostgroup update --id=<id for existing host group> --password=<new value>

This would be useful for automating provisioning scenarios via hammer.
