attachmnet_get_by_host|instance shouldn't require a volume_id

[John Griffith]

If I want to get attachments by instance, or by attached_host I shouldn't have to specify a volume-id.

    Remove volid from attachments_get_by_host|instance

    Attachments_get_by_host|instance should be just that, associating
    them with a specified volume-id doesn't really solve the problem.

    If that relationship is needed a simple get_by_volume will work with
    some inspection.

    This patch removes the volume_id arg from those get methods. A follow
    up patch will add get_all with filters for more complex relationships.
