Fix attach volume to instance repeatedly

1.When volume's status is 'attaching', controllermanager will attach
    it again and return err. So it is necessary to check volume's
    status before attach/detach volume.

   2. When volume's status is 'attaching', its attachments will be None,
    controllermanager can't get device path and make some failed event.
    But it is normal, so don't return err when attachments is None

Fix bug: #44536

[Federation] Refactor sync controller's reconcile method for maintainability

This PR refactors the sync controllers reconcile method for maintainability with the goal of eliminating the need for type-specific controller unit tests.  The unit test coverage for reconcile is not complete, but I think it's a good start.

coredns: support IPv6 record set

Added support for AAAA record for coredns and included unit test.
Refactored common test code to reduce duplication from added test and
existing tests.
Fixed function names in comments for Google and AWS tests to match
actual test name in this area.

Adding IPv6 support to kubernetes, once piece at a time. :)

**Special notes for your reviewer**:
In addition to the change and unit test method, I did some minor refactoring (since the UT was a near clone of an existing test). Fixed typos in related test methods' comment lines. Please let me know if this is OK (I was thinking it was a small change, but don't know the protocol here), or if I need to break it into multiple commits.

Support running StatefulSetBasic e2e tests with local-up-cluster

**What this PR does / why we need it**:

Currently StatefulSet(s) fail when you use local-up-cluster without
setting a cloud provider. In this PR, we use set the
kubernetes.io/host-path provisioner as the default provisioner when
there CLOUD_PROVIDER is not specified. This enables e2e test(s)
(specifically StatefulSetBasic) to work.

Make createEndpointService() and deleteEndpointService() plugin interface methods.

Why this change?

In some setups, after creation of dynamic PVs and before mounting/using these  PVs in a pod, the endpoint/service got mistakenly deleted by the user/developer. By making these methods 'plugin' specific, we can call it from mounter if there are scenarios where the endpoint and service got wiped in between accidentally.
