ThinLVM driver fails due to get_stats

[John Griffith]

The ThinLVM driver inherits get_stats info from the standard LVM driver. This unfortunately won't work because reading used capacity from a Thin provisioned LV is not done the same as with a regular LV obviously.

The ThinLVM driver should return it's own capabilities, including using the "infinite" designation for capacity and also the fact that it's thin provisioned :)

    Add capabilities reporting to ThinLVM driver

    ThinLVM driver was missing the newly required capabilities reporting
    and inheritance from the parent LVM driver doesn't work because the
    capacity reporting methods between regular LVM and Thin LVM are not
    compatible.

    This patch add the basic requirements needed in the capabilities reporting
    to make it usable by the filter scheduler.

    Fixes bug: 1166572
