Implement CanMount() for gfsMounter for linux
**What this PR does / why we need it**:
To implement CanMount() check for glusterfs. If mount binaries are not present on the underlying node, the mount will not proceed and return an error message stating so.
Related to issue : https://github.com/kubernetes/kubernetes/issues/36098
Related to similar change for NFS :
https://github.com/kubernetes/kubernetes/pull/36280
**Release note**:
`Check binaries for GlusterFS on the underlying node before doing mount`

Fix handling lists in kubectl convert
Fixes https://github.com/kubernetes/kubernetes/issues/36722
When handling multiple objects in `kubectl convert` (for example in `kubectl convert -f .` with multiple files in current directory) the objects must be managed as a list instead of individually, otherwise `-o yaml|json` will generate invalid format (just multiple json/yaml objects concatenated) which can't be fed to `kubectl create` like in `kubectl convert -f . | kubectl create -f -`.

Default host user namespace via experimental flag
@vishh @ncdc @pmorie @smarterclayton @thockin
Initial thought on the implementation https://github.com/kubernetes/kubernetes/pull/30684#issuecomment-241523425 wasn't quite right. Since we need to dereference a PVC in some cases the defaulting code didn't fit nicely in the docker manager code (would've coupled it with a kube client and would've been messy). I think passing this in via the runtime config turned out cleaner. PTAL

Use generous limits in the resource usage tracking tests
These tests are mainly used to catch resource leaks in the soak cluster. Using
higher limits to reduce noise.
This should fix#32942 and #32214.

Update Dashboard UI version to 1.4.2
**What this PR does / why we need it**:
Dashboard 1.4.2 contains a fix for an XSS security bug, so I think it would be prudent to update the Dashboard version 'shipped' with kubernetes to this version
**Special notes for your reviewer**:
**Release note**:
- Updated dashboard version in addons to 1.4.2```

Update OpenAPI spec generator to enable all APIs
scheduledjob/cronjob is missing in the OpenAPI spec located in api/openapi-spec/swagger.json. Root cause is the API was not enabled when we generate this file in hack/update-openapi-spec.sh.
This change is only effect static swagger.json file in our source tree but the documentation @pwittrock working on and client-python I am working on depends on it. We can sure hack our way through having this in our components, but it look cleaner to have it in 1.5 specially because there is no runtime behavior change of any kind.

Fix watching from resourceVersion=0 in etcd3 watcher
Fixes https://github.com/kubernetes/kubernetes/issues/36545
* Makes etcd3 consistent with watch cache behavior (all synthetic events sent for the initial list of items result in ADDED events)
* Fixes errors if previous values of initial items had been compacted away
* Removes fan-out Get() for previous values of initial items
Should be fixed before making etcd3 the default (https://github.com/kubernetes/kubernetes/pull/36229)

Fix strategic patch for list of primitive type with merge sementic
Fix strategic patch for list of primitive type when the patch strategy is `merge`.
Before: we cannot replace or delete an item in a list of primitive, e.g. string, when the patch strategy is `merge`. It will always append new items to the list.
This patch will generate a map to update the list of primitive type.
The server with this patch will accept either a new patch or an old patch.
The client will found out the APIserver version before generate the patch.
Fixes#35163, #32398

fix issue in reconstruct volume data when kubelet restarts
During state reconstruction when kubelet restarts, outerVolueSpecName
cannot be recovered by scanning the disk directories. But this
information is used by volume manager to check whether pod's volume is
mounted or not. There are two possible cases:
1. pod is not deleted during kubelet restarts so that desired state
should have the information. reconciler.updateState() will use this
inforamtion to update.
2. pod is deleted during this period, reconciler has to use
InnerVolumeSpecName, but it should be ok since this information will not
be used for volume cleanup (umount)
