Dependency on pyudev is unnecessary

[Darragh O'Reilly]

The pyudev package is only used in linuxbridge_neutron_agent.py to get a list of virtual network devices. This can be done without pyudev.

Fix proposed to branch: master
Review: https://review.openstack.org/66609

[Darragh O'Reilly (darragh-oreilly)]

The patch fixes the problem where testr cannot import the linuxbridge agent module because pydev was not in requirements.txt. You get:

Non-zero exit code (2) from test listing. stdout='\xb3)\x01@\x86@{neutron.tests.unit.agent.linux.test
         << skip pages of useless information >>
import errors4neutron.tests.unit.linuxbridge.test_lb_neutron_agent\x85\xc5\x1a\\', stderr=None
error: testr failed (3)
