kevin ffb701f8a3 Removed default lxc profile on container create
Having the lxc container create role drop the lxc-openstack apparmor
profile on all containers anytime its executed leads to the possibility
of the lxc container create task overwriting the running profile on a given
container. If this happens its likley to cause service interruption until the
correct profile is loaded for all containers its effected by the action.

To fix this issue the default "lxc-openstack" profile has been removed from the
lxc contianer create task and added to all plays that are known to be executed
within an lxc container. This will ensure that the profile is untouched on
subsequent runs of the lxc-container-create.yml play.
