Dan Prince a6dc322757 Move extension.py into quantum/api.
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.
