python 3.10+ upgrade: voltha-system-tests

https://gerrit.opencord.org/plugins/gitiles/voltha-system-tests/+/refs/heads/master

voltha-system-tests contains python virtualenv imports that are not usable to local devs with a new OS install or package manager installed binaries.

For release of python 3.10+ a change introduced during python 3.x has become a requirement and import of collections.abc has broken the robot framework in a few places.  Create a patch hierarchy allowing a current virtualenv install to be modified to function properly.
