SolidFire Attributes limited to 10 objects

[John Griffith]

Seems maybe we've gotten a bit carried away with stuffing data in the Volume Attributes. It looks like there are corner cases where we exceed 10 objects which is no good.

    Remove QoS settings from SolidFire attributes

    There's a limit in the number of parent key objects that
    are stored on the SolidFire cluster object attributes (10).

    While we're not hitting the limit yet, we're getting dangerously
    close, so this patch removes the unnecessary QoS keys that are
    currently added. These keys can safely be removed because they
    are stored by Cinder already and can be retrieved via the type
    setting, or in the case of retype, the retype info that's stored
    on the volume attribute.

    Other keys shouldn't be modified at this time because they are
    used internally by the driver to make various decisions, and
    turning them into sub-keys or removing them altogether will
    involve more far reaching changes that aren't necessary in the
    short term to fix this particular bug.
