Volume size could be specified to create volume
1. Provide a "volume_size" config at VolumeGroup
2. Make size as optional prameter, modify all volumes_client to
read the size from CONf if size is None.
3. Modify the testcase: test_volume_create_get_update
_delete_from_image to call create_volume with no size
parameter specified.
