[Ryan Harper <ryan.harper@xxxxxxxxxxxxx>]

There is an existing bug[1] and some nonce-cleanup changes coming (maas
will run nonce cleanup once a day IIRC).  In our heavily utilized MAAS in
OIL, it's not enough.

The 8 character nonce produces way too many collisions, we generated 65k
unique nonces in 30 minutes.

Greg (on CC) had a branch that replaced the none generator with
uuid.uuid4() which runs just as fast, but creates longer unique strings.
