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.

4fdd52b058 Update GetTopologyHints() API to return a map 
At present, there is no way for a hint provider to return distinct hints
for different resource types via a call to GetTopologyHints(). This
means that hint providers that govern multiple resource types (e.g. the
devicemanager) must do some sort of "pre-merge" on the hints it
generates for each resource type before passing them back to the
TopologyManager.

This patch changes the GetTopologyHints() interface to allow a hint
provider to pass back raw hints for each resource type, and allow the
TopologyManager to merge them using a single unified strategy.

This change also allows the TopologyManager to recognize which
resource type a set of hints originated from, should this information
become useful in the future.

bd925d6611 [TOB-K8S-027] Fix Incorrect isKernelPid check 
isKernelPid should explicitly check the error returned from os.Readlink and return true
only if the error value is ENOENT. Without this fix, if Readlink
returned say ENAMETOOLONG or EACESS, we would still count the process as
a kernel process (which is not true).

bc71c23bee [TOB-K8S-025] Incorrect docker daemon process name in container manager 
The container manager used in kubelet checks for docker daemon process either via pidfile
or process name. While the pidfile points to the docker daemon process PID, the
dockerProcessName constant stores a docker cli name ( docker ) instead of docker daemon
name ( dockerd ).
