[RFE] LinuxAdmin::Hosts API should support removal of hostnames and aliases

[jvlcek]

Currently LinuxAdmin::Hosts supports #add_alias and #set_canonical_hostname
It should also support #remove_alias #unset_canonical_hostname (method names TBD)

Also currently #set_canonical_hostname, by default, removes the hostname from
all addresses before setting it on only 1. Support to allow users to remove a hostname
from individual addresses but also to allow multiple addresses to be associated with
a single name
