Passing mandatory args as optional to create_volume

[Avishay Traeger]

Filter scheduler and create_volume flow both pass request_specs and filter_properties as optional arguments to create_volume in volume_rpcapi. This does not fit how the call is defined.

Also, the create_volume call in the migration code in manager.py should not allow rescheduling.

    Fix mandatory and optional args for create_volume

    Calls to create_volume (both volume_rpcapi and scheduler_rpcapi) pass
    mandatory args as optional and reverse. This patch fixes the calls to be
    according to the function definition.

    Also, fix the call to create_volume in the migration code where
    allow_reschedule defaults to True, but we don't pass request_spec so it
    prints a warning and disables it.
