0b168f0243 Change devicemanager to implement HintProvider.Allocate() 
This change will not work on its own. Higher level code needs to make
sure and call Allocate() before AddContainer is called. This is already
being done in cases when the TopologyManager feature gate is enabled (in
the PodAdmitHandler of the TopologyManager). However, we need to make
sure we add proper logic to call it in cases when the TopologyManager
feature gate is disabled.

a3f099ea4d Split devicemanager Allocate into two functions 
Instead of having a single call for Allocate(), we now split this into two
functions Allocate() and UpdatePluginResources().

The semantics split across them:

// Allocate configures and assigns devices to a pod. From the requested
// device resources, Allocate will communicate with the owning device
// plugin to allow setup procedures to take place, and for the device
// plugin to provide runtime settings to use the device (environment
// variables, mount points and device files).
Allocate(pod *v1.Pod) error

// UpdatePluginResources updates node resources based on devices already
// allocated to pods. The node object is provided for the device manager to
// update the node capacity to reflect the currently available devices.
UpdatePluginResources(
    node *schedulernodeinfo.NodeInfo,
    attrs *lifecycle.PodAdmitAttributes) error

As we move to a model in which the TopologyManager is able to ensure
aligned allocations from the CPUManager, devicemanger, and any
other TopologManager HintProviders in the same synchronous loop, we will
need to be able to call Allocate() independently from an
UpdatePluginResources(). This commit makes that possible.

bc686ea27b Update TopologyManager.GetTopologyHints() to take pointers 
Previously, this function was taking full Pod and Container objects
unnecessarily. This commit updates this so that they will take pointers
instead.

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.

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.
