b3741f344e The Pod is eligible to preempt when previous nominanted node is UnschedulableAndUnresolvable 
If the Pod's previous nominated node is UnschedulableAndUnresolvable from previous
filtering, it should be considered for preemption again.

2e1042f959 Use NodeWrapper to directly initialize node with labels 
Using NodeWrapper in the integration tests gives more flexibility when
creating nodes. For instance, tests can create nodes with labels or
with a specific sets of resources.

Also, NodeWrapper initialises a node with a capacity of 32 pods, which
can be overridden by the caller. This makes sure that a node is usable
as soon as it is created.

ec83143342 scheduler: merge Reserve and Unreserve plugins 
Previously, separate interfaces were defined for Reserve and Unreserve
plugins. However, in nearly all cases, a plugin that allocates a
resource using Reserve will likely want to register itself for Unreserve
as well in order to free the allocated resource at the end of a failed
scheduling/binding cycle. Having separate plugins for Reserve and
Unreserve also adds unnecessary config toil. To that end, this patch
aims to merge the two plugins into a single interface called a
ReservePlugin that requires implementing both the Reserve and Unreserve
methods.

f58abdf966 Use scheduler cache in affinity priority functions 
Make the cache implement NodeLister and expose it to the priority
functions. This way, the priority functions make use of a single cache,
the scheduler's, instead of mixing it with the lister's caches.

b864a5a808 Remove scheduler "TestGroup" utility. 
This util was used to fake certain aspects of apiserver behavior, such
as resource paths and JSON encoding. Our unit tests have been refactored
so they don't rely on the REST or JSON aspects of apiserver. This util
is no longer needed.
