SR-IOV tests: Schedule VM's on single node on connectivity tests
SR-IOV tests: Schedule VM's on single node on connectivity tests

On CI, we schedule SR-IOV lane jobs on nodes with SR-IOV hardware
with at least two PF's, each PF represents a physical port on the card.
We create containerized cluster with two worker nodes where each one
have single SR-IOV PF attached to their netns.

Tests that checks connectivity between VM’s may fail if the VM’s
are scheduled each on different node during the tests in case:
- SR-IOV PF's are not connected to each other or to the same network.
- SR-IOV card doesn't support or allow inter-connectivity between PF's.

By scheduling the VM's to the same node we prevent those tests
to fail, and remove this dependency on the environment.
