Bug description:
  [Impact]
  By default, all LXD containers will run with the same subuid/subgid range, which means that if a single container is compromised, all containers on the same host are potentially compromised as well.

  [Test Case]
  deploy a nova-lxd based openstack cloud
  boot multiple instances
  they all share the same uid/gid mapping within a host

  boot multiple instances with a flavor property of lxd:isolated
  all containers have different uid/gid mappings within a host

  [Regression Potential]
  Minimal in nova-lxd itself; we're just adding an additional extra-spec and tweaking the container profile if the underlying LXD daemon supports the isolation feature.

  [Original Bug Report]
  LXD 2.0.6 supports use of distinct sub-uid/gid for each running container; nova-lxd has support for this upstream in all stable and master branches so we should update nova-lxd in >= Xenial to support this feature.
