Updated git submodules

Project: optf/has master 4e2ee79d4dc2b25c396d6ffc5ac9c0845c492fc5

Fixed DuplicateOptError for latest oslo.config

Fixed the duplicate config in music/api.py which was occuring
when the oslo.config dependency is updated to the latest 6.0.0
Also removed psycopg2 dependency which was throwing warnings. psycopg2
is not really used during tests. So removing from test dependencies
