The "// import <path>" comment has been superseded by Go modules.
We don't have to remove them, but doing so has some advantages:
- They are used inconsistently, which is confusing.
- We can then also remove the (currently broken) hack/update-vanity-imports.sh.
- Last but not least, it would be a first step towards avoiding the k8s.io domain.
This commit was generated with
sed -i -e 's;^package \(.*\) // import.*;package \1;' $(git grep -l '^package.*// import' | grep -v 'vendor/')
Everything was included, except for
package labels // import k8s.io/kubernetes/pkg/util/labels
because that package is marked as "read-only".

return destroy func to clean up internal resources of storage
What?
Provide a destroy func to clean up internal resources of storage.
It changes **unit tests** to clean up resources. (Maybe fix integration test in another PR.)
Why?
Although apiserver is designed to be long running, there are some cases that it's not.
See https://github.com/kubernetes/kubernetes/issues/31262#issuecomment-242208771
We need to gracefully shutdown and clean up resources.

Move new etcd storage (low level storage) into cacher
In an effort for #29888, we are pushing forward this:
What?
- It changes creating etcd storage.Interface impl into creating config
- In creating cacher storage (StorageWithCacher), it passes config created above and new etcd storage inside.
Why?
- We want to expose the information of (etcd) kv client to cacher. Cacher storage uses this information to talk to remote storage.

make the resource prefix in etcd configurable for cohabitation
This looks big, its not as bad as it seems.
When you have different resources cohabiting, the resource name used for the etcd directory needs to be configurable. HPA in two different groups worked fine before. Now we're looking at something like RC<->RS. They normally store into two different etcd directories. This code allows them to be configured to store into the same location.
To maintain consistency across all resources, I allowed the `StorageFactory` to indicate which `ResourcePrefix` should be used inside `RESTOptions` which already contains storage information.
@lavalamp affects cohabitation.
@smarterclayton @mfojtik prereq for our rc<->rs and d<->dc story.
