Previously, it was possible for reusable CPUs and reusable devices (i.e.
those previously consumed by init containers) to not be reused by
subsequent init containers or app containers if the TopologyManager was
enabled. This would happen because hint generation for the
TopologyManager was not considering the reusable devices when it made
its hint calculation.
As such, it would sometimes:
1) Generate a hint for a differnent NUMA node, causing the CPUs and
devices to be allocated from that node instead of the one where the
reusable devices live; or
2) End up thinking there were not enough CPUs or devices to allocate and
throw a TopologyAffinity admission error
This patch fixes this by ensuring that reusable CPUs and devices are
considered as part of TopologyHint generation. This frunctionality is
difficult to unit test since it spans multiple components, but an e2e
test will be added in a subsequent patch to test this functionality.
