The support for LXC/LXD was added as part of the initial effort
to develop a container driver for Manila which was later on
abandoned. Despite of that, the code in the manila-image-elements
remained.
This patch set removes LXC/LXD container support in
manila-image-elements. Code-path used for generation of Docker images is
preserved.
This will help for the parallel effort of making
manila-image-elements usable by end users.
