This change moves extensions.py out of the extensions module and into the api module. This resolves an issue where the following log WARNING message would occur each time the Quantum API starts: Did not find expected name "Extensions" in /usr/lib/python2.7/site-packages/quantum/extensions/extensions.py Fixes LP Bug #1074895.
