Given functional metadata service,
ssh key injection from the host is not necessary for ubuntu images.

Ubuntu cloud images do not have any ssh HostKey generated inside them
(/etc/ssh/ssh_host_{ecdsa,dsa,rsa}_key). The keys are generated by
cloud-init after it finds a metadata service. Without a metadata service,
they do not get generated. ssh will drop your connections immediately
without HostKeys.
This is arguably a bug, and there is an open bug to have the keys
generated independent of ability to find a metadata service
(http://pad.lv/906669).

Fix the metadata issue, you're going to want it.
Alternatively, use configdrive
