lxc snapshot allows a ':' in snapshot name

[Ron Knapp]

Package info:

lxd 2.0.0-0ubuntu4 amd64 Container hypervisor based on LXC - daemon

on 16.04 LTS

When you create a snapshot of a container with command

lxc snapshot [remote:]<source> <snapshot name> [--stateful]

The command allows you to use a ':' in the snapshot name, once the snapshot is created it
can no longer be manipulated because all the other command treat the : as a remote reference.

lxc snapshot www nuc2:wwwsnap0

Snapshots:
  snap0 (taken at 2016/05/23 22:18 UTC) (stateless)
  nuc2:wwwsnap0 (taken at 2016/05/24 02:30 UTC) (stateless)

lxc delete www/nuc2:wwwspan0

error: unknown remote name: "www/nuc2"

The only way I could delete it that I found was to update the row in the container table of
/var/lib/lxd/lxd.db and change the name to a valid one. This was the result trying to create a snapshot on a remote.

stgraber@castiana:~$ lxc snapshot test a:b
stgraber@castiana:~$ lxc restore test a:b
stgraber@castiana:~$ lxc delete local:test/a:b

So this all works as expected. If the name may be confused for a remote, then the remote name becomes mandatory. This is typically "local:" (can be checked with lxc remote list) and when properly prefixed with it, everything works.
