0639bd0942 Change CPUManager containerMap to key off of (podUID, containerName) 
Previously it keyed off of a pointer to the actual pod / container,
which was unnecessary, and hard to work with (especially on the
retrieval side).

0c5c3d8bb9 Remove pkg/util/mount (moved out of tree) 
This patch removes pkg/util/mount completely, and replaces it with the
mount package now located at k8s.io/utils/mount. The code found at
k8s.io/utils/mount was moved there from pkg/util/mount, so the code is
identical, just no longer in-tree to k/k.

1fd8921546 Move mount/fake.go to mount/fake_mount.go 
This patch moves fake.go to mount_fake.go, and follows to principle of
always returning a discrete type rather than an Interface. All callers
of "FakeMounter" are changed to instead use "NewFakeMounter()". The
FakeMounter "Log" struct member is changed to not be exported, and
instead only access through a new "GetLog()" method.

58f3554ebe Sync all CPU and device state before generating TopologyHints for them 
This ensures that we have the most up-to-date state when generating
topology hints for a container. Without this, it's possible that some
resources will be seen as allocated, when they are actually free.

d9adf20360 Abstract removeStaleState from reconcileState in CPUManager 
This will become especially important as we move to a model where
exclusive CPUs are assigned at pod admission time rather than at pod
creation time.

Having this function will allow us to do garbage collection on these
CPUs anytime we are about to allocate CPUs to a new set of containers,
in addition to reclaiming state periodically in the reconcileState()
loop.

all merge strategies, with specific test cases being able to be
specified on a policy-by-policy basis.

5f7db54d3c Move function from top-level TopologyManager to best-effort policy 
This is in preparation for removing the special-case of the
SingleNumaNode policy in mergeProvidersHints() in favor of a custom
merging strategy with much less overhead.

d95464645c Add Merge() API to TopologyManager Policy abstraction 
This abstraction moves the responsibility of merging topology hints to
the individual policies themselves. As part of this, it removes the
CanAdmitPodResult() API from the policy abstraction, and rolls it into a
second return value from Merge()

6fd8a6eb69 Make restricted TopologyManager policy inherit from best-effort policy 
These policies only differ on whether they admit the pod or not when a
TopologyHint is preferred or not. As such, the restricted policy should
simply inherit whatever it can from the best effort policy and only
overwrite what is necessary.

This does not matter for now, but will become important when we add a
new 'Merge()' abstraction to a Policy later on.
