Make feature gate enablement checks lock-free

TestIoHandler should not run on unsupported platforms
Fix for failing test on darwin/osx. Skip the test on unsupported (non-windows and non-linux) platforms.
**What this PR does / why we need it**:
`make test WHAT=./pkg/volume/azure_dd` doesn't pass on my OSX setup (10.12.6, go1.9, docker 17.06.2) on master. Our [docs on unit tests](https://github.com/kubernetes/community/blob/master/contributors/devel/testing.md#unit-tests) say they should pass on OS X. This PR allows it to pass.

Add an option for turning on/off compaction from apiserver in etcd3 mode
…erver
**What this PR does / why we need it**:
This commit adds an option for controlling request of compaction to
etcd3 from apiserver. There is a situation that apiserver cannot fully
own its etcd cluster (e.g. sharing it with canal). In such a case,
apiserver should have limited access in terms of etcd's auth
functionality so it don't have a privilege to issue compaction
requests. It means that the compaction requests should be issued by
other component and apiserver's compaction requests are needless.
For such use cases, this commit adds a new flag
storagebackend.Config.DoCompaction. If the flag is true (default),
apiserver issues the compaction requests like current behaviour. If it
is false, apiserver doesn't issue the requests.
**Related issue (etcd)**

**Release note:**
```release-note
Add --etcd-compaction-interval to apiserver for controlling request of compaction to etcd3 from apiserver.
```
The e2e iPerf test case currently only runs in IPv4 mode.
This change add an option to run an iPerf test in IPv6 mode (i.e. by running
iPerf with a "-V" command line flag), so that the test can be run on
IPv6-only clusters.

Disable autoscaling before removing autoscaled node pool
This is to prevent flakes due to API calls failing in AfterEach during master restart, which is triggered by deleting an autoscaled node pool. Adding disable call before deleting node pool should prevent this as we'll wait for master restart in disableAutoscaler function.
While it may be faster to wait after deletion of autoscaled node pools, this is less complex and will be easier to remove in the future when changing autoscaling setttings no longer triggers master restart.

Change RBAC storage version to v1 for 1.9
v1 was introduced in 1.8, but storage version remained at v1beta1 to accommodate HA rolling upgrades. in 1.9, we can change the persisted and preferred version to v1
```release-note
RBAC objects are now stored in etcd in v1 format. After completing an upgrade to 1.9, RBAC objects (Roles, RoleBindings, ClusterRoles, ClusterRoleBindings) should be migrated to ensure all persisted objects are written in `v1` format, prior to `v1alpha1` support being removed in a future release.

Implement CRI stats in Docker Shim
**What this PR does / why we need it**:
This PR implements CRI Stats in the Docker Shim. It is needed to enable CRI stats for Docker and ongoing /stats/summary API changes in moving to use CRI.
Related issues:
#46984 (CRI: instruct kubelet to (optionally) consume container stats from CRI)
#45614 (CRI: add methods for container stats)
This PR is also a followup to my original PR (https://github.com/kubernetes/kubernetes/pull/50396) to implement Windows Container Stats. The plan is that Windows Stats will use a hybrid model: pod and container level stats will come from CRI (via dockershim) and that node level stats will come from a "winstats" package that exports cadvisor like datastructures using windows specific perf counters from the node. I will update that PR to only export node level stats.

Major changes:
- Don't generate a patch, instead generate the merged object so it can be used with PUT
- Separate tree parsing logic to collate items in a list from the delete / merge / replace / add logic when merging
- Use openapi for merge strategy metadata so it works with extensions and version skew
- Support multi-field mergekeys when merging lists
- Support replace strategy for maps
- Reduce complexity of generating order when merging lists - keep the locally defined order and append remote only-items
Continue to support:
- Explicitly setting fields to null
- Merging lists of primitives
- Don't randomize ordering when merging lists
TODO:
- Retain keys
- Conflict detection
