Add envelope encryption transformer

Essential to implement envelope encryption, using a KEK-DEK based encryption scheme which uses an external root of trust (cloudkms, hardware etc).

* Caches known DEKs.
* Creates a new DEK for each write (most common and recommended way of implementing envelope encryption).
* Relies on an implementation of `envelope.Service` which actually implements the encryption and decryption using the external root of trust.

Essential for #48522

This PR is generic, and independent of any cloudprovider / cloud / KMS code.

Do not generate warning event on dns search deduplication

In the case that the node is able to use the cluster DNS, `cluster.local` will already be in the node search domains in `/etc/resolv.conf`.  The kubelet then parses `/etc/resolv.conf` on the node and combines it with  $namespace.svc.$clusterDomain, svc.$clusterDomain, and $clusterDomain to create the pod DNS search domains.  clusterDomain is `cluster.local` by default.  This causes the code to generate a Warning event visible to the user for _every_ pod:

```
Warning   DNSSearchForming     Found and omitted duplicated dns domain in host search line: 'cluster.local' during merging with cluster dns domains
```
This is really overkill.  IMHO, this should be done in the background with no user level notification or logging at all.

Set external hostname in local-up-cluster

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

If we set --external-hostname, then the api server does not look
in the CloudProviderOptions.DefaultExternalHost method. While we
are at it, let's log an info message, so if there is a failure
the operator gets a hint that they can use --external-hostname
to bypass the lookup in the cloud provider. This will enable us
to set the CLOUD_PROVIDER to openstack for example and not have to
really run api server inside a openstack vm.

Fix bug in cluster/log-dump

We're breaking in case KUBECTL is set as "./cluster/kubectl.sh --match-server-version". Moreover we always are using cluster/kubectl.sh as the default and don't want to do match-server-version for the purpose of logexporter.

Also adding owners file so I'm not blocked for approves while making fixes in log-dump. Besides I'll be able to review fixes sent by others.
