Automatic merge from submit-queue

Ensure that assumed pod won't be expired until the end of binding

In case if api server is overloaded and will reply with 429 too many requests error, binding may take longer than ttl of scheduler cache for assumed pods 1199d42210/pkg/client/restclient/request.go (L787-L850) 

This problem was mitigated by using this fix e4d215d508 and increased rate limit for api server. But it is possible that it will occur again.

Dmitry Shulyak 530ee716e3 Count ttl for assumed pod when binding is finished 
In such cases when api server is overloaded and returns a lot of
429 (too many requests) errors - binding may take a lot of time
to succeed due to retry policy implemented in rest client.
In such events cache ttl for assumed pods wasn't big enough.

In order to minimize probability of such errors ttl for assumed pods
will be counted from the time when binding for particular pod is finished
(either with error or success)

Connor Doyle c93646e8da Support opaque integer resource accounting. 
- Prevents kubelet from overwriting capacity during sync.
- Handles opaque integer resources in the scheduler.
  - Adds scheduler predicate tests for opaque resources.
- Validates opaque int resources:
  - Ensures supplied opaque int quantities in node capacity,
    node allocatable, pod request and pod limit are integers.
  - Adds tests for new validation logic (node update and pod spec).
- Added e2e tests for opaque integer resources.

PingWang 85f1e0ea6a Fix the bug of the "removePod" function in node_info.go 
It should reduce the resource data after finding the pod in the pods, because perhaps no corresponding pod in the pods of the node, at this time it shouldn't reduce the resource data of the node.

Rudi Chiarito 362c763fca WIP v0 NVIDIA GPU support 
Implements part of #24071

I am not familiar with the scheduler enough to know what to do with the scores. Punting for now.

support and user docs
