Title:
  nova docker virt driver does not support lxc options

Status in Nova Docker Driver:
  Confirmed

Bug description:
  The current implementation of the docker virt drive does not support
  passing any lxc options through to docker. For example I may want to
  pass through lxc.cgroup.blkio.throttle.read_bps_device or some other
  lxc cgroup option.. There is not way to do this right now, nor are any
  of the mem/cpu specs on the flavor honored..

  I'm not an expert on in this space, but seems like the docker driver
  should support generic lxc/docker options in the form or flavor
  extras.

  For example any flavor extras starting with 'docker.' could be transformed to docker options. Example a flavor extra like:
  docker.cidfile = /tmp/cpid

  would get translated into the docker -cidfile argument for the
  container run..

  And for example I could add a flavor extra like:

  docker.lxc-conf='lxc.cgroup.blkio.throttle.read_bps_device=8:0
  10485760'

  which would get passed to dockers lxc-conf argument.

  Obviously the above format is not thought out, but to harness the
  limits of containers we need the ability to set lxc and docker config
  options/limits.
