refactor cache manager for yurthub
<!-- 
Please make sure you have read and understood the contributing guidelines;
https://github.com/openyurtio/openyurt/blob/master/CONTRIBUTING.md -->

### Ⅰ. Describe what this PR does

#### Backgound:
1.  list requests from edge node have three types:
 - type1: only get specified object by using `fieldselector=metadata.name=xxx`, the request path like: `https://{ip:port}/api/v1/namespaces/default/pods?fieldselector=metadata.name=xxx`
 - type2: get a kind of objects by using  `fieldselector=spec.nodeName=xxx` or `labelselector=foo=bar`, the request path like: `https://{ip:port}/api/v1/pods?fieldselector=spec.nodeName=xxx`
 - type3: get all pods, the request path like: `https://{ip:port}/api/v1/pods`

2. cache manager handles list request in yurt-hub:
- in yurthub cache manager, we cache object one by one for list response, and the code link: https://github.com/openyurtio/openyurt/blob/master/pkg/yurthub/cachemanager/cache_manager.go#L336
- for type2 list request, query cache handle is the same as type3 list request, and the code link: https://github.com/openyurtio/openyurt/blob/master/pkg/yurthub/cachemanager/cache_manager.go#L167

#### problem:
- response for type3 list will not update all caches on local disk, so some deleted objects will remain in the cache.
- if a client on edge node has both type2 and type3 list request, a error will occur for type2 response.

#### solution:
1. replace local cache response instead of one by one cache for type2 and type3 list request
2. fix cache conflict for type2 and type3 list request, a client can only support one type list request  for one resource in type2 and type3。and at present, kubelet/kube-proxy/flannel/coredns have only one type list request for one resource in type2 and type3.

### Ⅱ. Does this pull request fix one issue?
<!--If so, add "fixes #xxxx" below in the next line, for example, fixes #15. Otherwise, add "NONE" -->


### Ⅲ. List the added test cases (unit test/integration test) if any, please explain if no tests are needed.


### Ⅳ. Describe how to verify it
make test
make all
and make sure yurthub cache manager can work


### Ⅴ. Special notes for reviews
