Exit on failure to load mechanism drivers
By using the on_missing_entrypoints_callback and
on_load_failure_callback options[1] we can call a handler for the
missing driver error properly.
As the bug states, I logged it as a critical failure and terminated
the neutron server.
I used SystemExit, I wasn't sure if there was a more graceful way
of exiting.

Title:
Failure to load mechanism drivers in ML2 should be critical
Status in neutron:
Fix Released
Bug description:
Right now when ML2 load mechanism driver, if some of them is
unavailable (due to typo or bug in the driver, preventing it to be
loaded by stevedore), it registered only in 'info' output of neutron-
server ('Configured mechanism driver names' and 'Loaded mechanism
driver names').
I believe inability to initialize any on given mechanism drivers is
grave and fatal for neutron server. Server without proper mechanism
driver will silently made all relevant port bindings 'binding_failed',
causing harm and chaos in production environment.
Proposition:
terminate neutron-server with CRITICAL failure if some of
cfg.CONF.ml2.mechanism_drivers is unavailable.
This is a big issue for operators, because, currently, such
misconfigurations are REALLY hard to debug, especially in conjuncture
with broken mechanism drivers.
