openapi: Change references to be first-class
**What this PR does / why we need it**:
References in the openapi are currently completely hidden from the
model, and just passed through as we walk the tree. The problem is that
they can have a different description and more importantly, different
extensions.
Change them to be first-class citizen, and fully part of the model. It
means that visitors have to implement one more function and decide if
something specific should be done with references. Validation is updated
to just completely ignore them and passthrough (like it was done
before).

We seem to get a lot of flakes due to "connection refused" while running
`kubectl exec`. I can't find any reason this would be caused by the test
flow, so I'm adding retries to see if that helps.

kubeapiserver: rename `--experimental-bootstrap-token-auth` to `--enable-bootstrap-token-auth`.
#**What this PR does / why we need it**:
This change renames the API server `--experimental-bootstrap-token-auth` flag to `--enable-bootstrap-token-auth`. The old flag is accepted but generates a warning.
In 1.9, we will drop support for `--experimental-bootstrap-token-auth` entirely.
#### Example of the warning log:
```
$ kube-apiserver --experimental-bootstrap-token-auth --etcd-servers https://127.0.0.1:1234 --service-cluster-ip-range 10.0.1.0/24
Flag --experimental-bootstrap-token-auth has been deprecated, use --enable-bootstrap-token-auth instead.
[...]
```
**Which issue this PR fixes** fixes https://github.com/kubernetes/kubernetes/issues/50613
**Release note**:
```release-note
Renamed the API server flag `--experimental-bootstrap-token-auth` to `--enable-bootstrap-token-auth`. The old value is accepted with a warning in 1.8 and will be removed in 1.9.

**Release note**:
```release-note
Azure file persistent volumes can use a new `secretNamespace` field to reference a secret in a different namespace than the one containing their bound persistent volume claim. The azure file persistent volume provisioner honors a corresponding `secretNamespace` storage class parameter to determine where to place secrets containing the storage account key.

The change assumes the compute Alpha object is the superset of the v1
object. By storing the Alpha objects internally in the fake, we can
convert them to Beta and v1 to test different functions.
