Bug description:
  The cephx identities, which the charms generate for glance, cinder and
  nova-compute, have excessive capabilities. They allow write access to
  mons, and unrestricted access to OSDs.

  The following caps should be sufficient:

  For client.glance:
  mon = "allow r"
  osd = "allow rw pool=glance"

  For client.cinder:
  mon = "allow r"
  osd = "allow rw pool=cinder"

  For client.nova-compute:
  mon = "allow r"
  osd = "allow rwx pool=cinder"
