Previously, sudo-requiring functional tests hardcoded the use of
'sudo' as the root helper. Devstack gate jobs do not allow
password-less invocation of 'sudo', though, so such tests were unable
to run in the gate. This patch adds the ability to configure the
rootwrap command installed by devstack by setting the OS_ROOTWRAP_CMD
environment variable in the test execution environment, allowing
sudo-requiring tests to run.

The ovsdb tests check the output of "ovsdb-client monitor" before and after
some operations. The first line of output is a header row with spaces for
column separation. The column widths can vary depending on the data in the
columns, so compress multiple spaces to one for testing.

The current method of checking openvswitch and kernel versions for
specific feature support is brittle, distro-specific and unsupportable.
This patch removes the runtime version checks and implements a test
script which allows testing specific neutron features or can test
that all features required by a specific configuration are available.
For example, to test VXLAN support in openvswitch, either:
neutron-sanity-check --ovs_vxlan
or pass in the deployed configuration files with AGENT/tunnel_types
containing 'vxlan', like:
neutron-sanity-check --config-file /etc/neutron/plugins/ml2.conf.ini
Deployment tools can then test that the required features exist without
relying on version numbers and without incurring a penalty every time
the agent is started.

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()

This commit adds a functional test to verify host VXLAN support. It compares
the results of this functional test with the logic in ovs_lib to ensure both
report the same values.

Refactor the functional tests a bit to add a common base class for agent
tests. This is needed an upcoming commit which adds a functional test
for VXLAN version checking.

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.

If minimize_polling=True and the ovsdb-client process died, the
default respawn interval of 0 would mean that we'd start polling
again. This patch adds the option ovsdb_monitor_respawn_interval and
defaults it to 30 seconds.

To ensure that correct process is killed when using a rootwrap
script, we must recursively list the children of our top-level
process and kill the last one. This patch uses the psutil python
module which is already used in the heat-cfntools project.

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.
