allow admiral to ssh to any container as admiral

starphleet-lxc-ssh is a new file that takes as arguments an order name and optional a command to run on the container.
 
starphleet-containermake changes are to mount the ships /home/admiral and create just the folder /home/admiral on the new container. Also, on the new container we add the admiral user since the containder will not have a uid for admiral when we chown the folder. 

In tools we create a private/public key that we then cat to the auth file.
