update ovs plugin

[Eric Desrochers]

[Impact]

The Openvswitch plugin is a little outdated.

sosreport is in constant development, and since 3.9.1 got released a few plugin updates, adds, ... has been merged upstream (Some changes has been reported and/or submitted by Canonical employees). Some changes will be beneficial for the Canonical support team in order to help troubleshooting UA customer and may also serve for other 3rd party vendor.

[Test Case]

* Install sosreport
* Run sosreport in different customer scenarios:
server, desktop, cloud, hypervisor, instance (container, vm), physical server, ...
* Extract archive and look at the content, look for 0 size file (and use common sense if legit or not)
* Look under "sos_reports" for full report.
* Look under "sos_logs" for warnings/errors.
  $ grep -v "INFO:" sos_logs/sos.log
* Run "simple.sh": A quick port of the travis tests to bash. Generating various type of sosreports collection (which is part of the autopkgtest (d/test/simple.sh) now.

[Regression Potential]

Sosreport, as of today, has ~300 plugins that are all configured differently and configured to run under certain conditions. We can't test all possible scenarios. All we can do is identify the most common, important and Ubuntu/Canonical related one and test them (e.g. Openstack*, juju, MAAS, kernel, ...). With that being said, it is definitely possible that certain plugins may not work as expected, but the risk will be very low (e.g. not collecting the desired information) and isolated to this specific plugin. It shouldn't affect the other plugins nor core functionalities of sosreport.
