set api.extensions logging to ERROR in unit tests

neutron.api.extensions generates a lot of output in a normal
unit test run. It's responsible for > 80% of the lines in the
subunit_log.txt. Logging each file load 10k times slows everything
down, takes up valuable memory, and doesn't really help with testing.

Instead we can set this to ERROR level in a fixture to ignore most
of that logging and help make the unit tests run faster.
