87cd496a29 scheduler/framework: introduce pluggable SharedDRAManager 
SharedDRAManager will be used by the DRA plugin to obtain DRA
objects, and to track modifications to them in-memory. The current
DRA plugin behavior will be the default implementation of
SharedDRAManager.

Plugging a different implementation will allow Cluster Autoscaler
to provide a simulated state of DRA objects to the DRA plugin when
making scheduling simulations, as well as obtain the modifications
to DRA objects from the plugin.

wasn't obvious when reading the documentation.

DRA: scheduler event handlers via assume cache

9a6f3b9388 scheduler: central ResourceClaim assume cache 
This enables connecting the event handler for ResourceClaim to the assume
cache, which addresses a theoretic race condition.

It may also be useful for implementing the autoscaler support, because now
the autoscaler can modify the content of the cache.

2c205e291d Distinguish unschedulable with unresolvable in scheduler 
Before, in RunPostFilterPlugins, we didn't distinguish between unschedulable and unresolvable
because we only have one postFilterPlugin by default, now, we have at least two, we should
make sure that once a postFilterPlugin returns unresolvable, we'll return directly

49e7e80999 Modify the return type of RunFilterPlugins to *Status 
Before, the return type of RunFilterPlugins is a Map, but considering we'll return immediately
once we met unsuccessful status, this is not necessary.
