Hold Pod in cache until all other cleanup work is completed 
- Move "ForgetPod" after "RunReservePluginsUnreserve", so that the cache would hold the pod to
  avoid it's being retried simutaneously until Unreserve is completed.
- Move "assume" ahead of "RunReservePluginsReserve". This is based on the fact that "ForgetPod" is
  the last step of failure path, so "assume" should be reversly treated as the first step. The
  current failure path is like this:
  assume -> reserve -> unreserve -> forgetPod -> recordingFailure
- Make subtests of TestReservePluginUnreserve stateless

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.

1b223b861a scheduler: run Unreserve if Reserve fails 
If a reserve plugin's Reserve method returns an error, there could be
previously allocated resources from successfully completed reserve
plugins that must be unallocated by the corresponding Unreserve
operation. Since Unreserve operations are idempotent, this patch runs
the Unreserve operation of ALL reserve plugins when a Reserve operation
fails.

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.
