5501f542cd Fixed bug in TopologyManager with SingleNUMANode Policy 
This patch fixes an issue in the TopologyManager that wouldn't allow
pods to be admitted if pods were launched with the SingleNUMANode policy
and any of the hint providers had no NUMA preferences.

This is due to 2 factors:

1) Any hint provider that passes back a `nil` as its hints, has its hint
automatically transformed into a single {11 true} hint before merging

2) We added a special casing for the SingleNumaNodePolicy() in the
TopologyManager that essentially turns these hints into a
{11 false} anytime a {11 true} is seen.

The current patch reworks this logic so the that TopologyManager can
tell the difference between a "don't care" hint and a true "{11 true}"
hint returned by the hint provider. Only true "{11 true}" hints will be
converted by the special casing for the SingleNumaNodePolicy(), while
"don't care" hints will not.

This is a short term fix for this issue until we do a larger refactoring
of this code for the 1.17 release.

e35301c19f Rename package socketmask to bitmask. 
- As discussed in reviews and other public channels,
  this abstraction is used to represent numa nodes, not sockets.
- There is nothing inherently related to sockets in this package anyway.

5ed80dadcf Update CanAdmitPodResult() in TopologyManager to take a TopologyHint 
Previously it only took a bool, which limited the logic it could perform
to determine if a pod should be admitted or not based on the merged hint
from the policy.

ecc14fe661 Update CPUManager to include NUMANodeID in CPUTopology 
Unfortunately, the NUMA information is not readily available from
cadvisor, so we have to roll the logic to discover it by hand. In the
future, we should remove this custiom code to use the information
provided by cadvisor once it is made available.
