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. Partial-Bug: #1177973 Change-Id: I9969e556acecf7a9e77d873371cc2ec2647be011
