    Add support for backing up volume metadata

    This commit adds a new versioned api to the backup driver base
    class which all backup driver implementations should use in order
    to support backing up volume metadata as well as data. The general
    rule here is that we backup all metadata from a set of db tables
    and can then be selective about what we restore.

    As part of this commit, Ceph backup driver implements the new api
    to backup volume metadata (including glance metadata) thus
    supporting restoring volumes as bootable.

    It is expected that the other backup driver implementations will
    follow suit and adopt this approach.
