uuid does not work

[wrobell]

while uuid support was added to storm over a year ago it still does not work
- it is not exposed via storm.locals
- using UUID from storm.properties gives following error when saving to postgres database
psycopg2.DataError: invalid input syntax for uuid: "\x3539613038656537323463613463343162316665363264346263616333656265"

This looks like it is related to bug 585704.

UUIDVariable.parse_get() converts the value to a byte string, which then gets wrapped in a psycopg2.Binary(), which with modern versions of psycopg2 interpolate with a bytea cast. The code should be returning a unicode string instead, since it is a textual representation of the UUID.

The fact that I didn't pick this up when fixing the other related issues would indicate that the test coverage is lacking.
