TO properly implement some e2e tests, we need to know
some basic topology facts about the system running the tests.
The bare minimum we need to know is how many PCI SRIOV devices
are attached to which NUMA node.
This way we know which core we can reserve for kube services,
and which NUMA socket we can take to test full socket reservation.
To let the tests know the PCI device topology, we use annotations
in the SRIOV device plugin ConfigMap we need anyway.
The format is
```yaml
metadata:
annotations:
pcidevice_node0: "2"
pcidevice_node1: "0"
```
with one annotation per NUMA node in the system.

This patch extends and completes the previously-added
empty topology manager test for single-NUMA node policy
by adding reporting in the test pod and checking
the resource alignment.
