H302 violation is reported by flake8 when importing separated objects from
modules instead of importing the whole module.
e.g. from package.module import function
function()
is changed to
from package import module
module.function()

in python3.x, there is no method named xrange(),
it has replaced by range(),which is equal to xrange() in python2.x.
so we must fix this issue.we use six module to fix this issue.

This change adds the ability to monitor the local ovsdb for
interface changes so that the l2 agent can avoid unnecessary
polling. Minimal changes are made to the agent so the risk
of breakage should be low. Future efforts to make the agent
entirely event-based may be able to use OvsdbMonitor as a
starting point.
By default polling minimization is not done, and can only be
enabled by setting 'minimize_polling = True' in the ovs
section of the l2 agent's config file.

Interacting with a long-running asynchronous process requires the
use of non-blocking io. This change adds a helper class that can
launch a long-running process and read stdout and stderr in a
non-blocking fashion via eventlet.
This functionality is intended to support monitoring ovsdb via
a long-running and root-privileged invocation of ovsdb-client.
The complexity of the system interaction in this patch suggested
the addition of a functional test that validated actual behaviour.
The test was added under the neutron/tests/functional path which
is now included in the testr search path.
