hostname not set via metadata

[chorrell]

Passing a metadata "hostname" value does not set the hostname for an lx-brand container.

The guest tools should retrieve that value, if available, and set it accordingly in the container

[sjorge]

Perhaps it should set hostname and domainname? (assuming a fqdn is provded)
Probably needs some decent though as the docs for RHEL (centos) and debian (debian/ubuntu) seem to not agree on best practices: http://serverfault.com/questions/331936/setting-the-hostname-fqdn-or-short-name

[razamatan]

there should be something equivalent done for dhcp interfaces in lx zones where the /etc/hostname.${iface} is set to "inet $(mdata-get sdc:hostnaem)".
