prior to my enabling of the clone hook, the setting of the hostname
was being done by writing to /etc/hostname. Instead of relying on that
we're now writing 'local-hostname' into the metadata for the instance.
cloud-init then reads this and sets the hostname properly.
We are also writing /etc/hostname with the new hostname explicitly. This is
useful/necessary because on network bringup of eth0, dhclient will submit its
hosname. The updating done by cloud-init occurs to late, and thus
the dhcp request goes out with the un-configured hostname and dns doens't
work correctly.
