Attaching a volume w/ an invalid (too long) UUID results in HTTP 500.

[Eric Harney]

There is some validation here, but it doesn't seem to be complete:
$ nova volume-attach ad1f16cc-d859-4f9d-a7b5-12d28d7ac53c 11111111-2222-4f9d-5555-6
ERROR (BadRequest): Invalid input for field/attribute volumeId. Value: 11111111-2222-4f9d-5555-6. u'11111111-2222-4f9d-5555-6' is not a 'uuid' (HTTP 400)

$ nova volume-attach ad1f16cc-d859-4f9d-a7b5-12d28d7ac53c 11111111-2222-4f9d-5555--666666666666

(note the double hyphen)
