Fixing Arista CLI command

A minor change is made to the Arista API between ML2 Driver and the
back-end. This fix addresses this change to align Icehouse release with
Arista EOS releases.

Revert changes removing OVSBridge return

This reverts changes from this review [1] which incorrectly removed
the return of the OVSBridge object when calling BaseOVS.add_bridge.
This broke all functional tests relying on this return.

Explicitly import state_path opt in tests.base

This wasn't explicitly needed in the unit tests because
neutron.common.config was already loaded, but this broke for the
functional tests (which are non-voting) so add a CONF.import_opt line so
functional tests know where to find the definition for state_path.
