Decrease default node schedulable timeout in e2e framework
This seems to have been introduced earlier primarily because in large clusters some nodes are waiting on route creation.
But now, with all our large-scale tests moved to IP-aliases we are much faster (typically <5m) in having the nodes schedulable.

remove decoder from name printing
The extra decoding step inside of name printing isn't useful. It's only current utility is when the content inside of the list is a runtime.Unknown. However, when you're making use of this printer in a CLI, you've read the content in via a builder or a scheme directly. You would logically set this decoder based on that same scheme. If you were unable to decode using the scheme before, you'll simple be unable to do it again here.
Near as I can tell, this would only be useful if objects weren't decoded before printing. There is a unit test that ensures this remains. I'd like to see if any practical tests (cmd, e2e) rely on it.
@smarterclayton @liggitt not many people would have written it to begin with. One of you?

Clean stackdriver sinks when reached limit
Workaround for stackdriver sinks leaking during test.
This will automate cleaning when sinks when we reach limit.
It can cause other tests running in parallel to fail, but because it's happens once per month impact is negligible.

apiextensions: normalize CR validation to return multiple errors
Deduplicated and use of the `allErrs` pattern we have elsewhere.
Updates dynamic Kubelet config to use a structured status, rather than a
node condition. This makes the status machine-readable, and thus more
useful for config orchestration.

For now the config structs and validation are left as-is and
the LoginByToken method is used if the username value is PEM encoded.
In this case of username field configured with the public key, the password
field is expected to be configured with the private key.
In a follow-up PR we can look at collapsing the auth related fields into
a common struct to avoid duplication of field merging and validation.
And then add separate fields for the public and private keys.

scheduler: remove nested retry loops and fix serving metrics under healthz server port
This PR fixes the issues of #63404:
- The Serve func for metrics and healthz does not block. Inside, there is a retry loop. This PR fixes this and gets rid of the error messages every 5 seconds.
- The separate metrics server is only to be started if it is configured on another port. Before this PR we were wrongly checking for the healthz service to be activated and then launched the metrics server instead. Because both server startups are in a go routine, they were racing against each other. If you were unlucky, the metrics endpoint was winning and it returned 404 on /healthz (while it should not have been active in the first place). The kubemark tests run the scheduler with a liveness probe which failed, restarting the scheduler after some minutes.

add timeout for exec interface
This should get us away from situations like https://github.com/kubernetes/kubernetes/issues/63331.
A little bit more context, the `os/exec` package starts to accept `context.Context` in golang 1.7. We should leverage that so we can have a more predictable behavior, then.

Stop installing kubeadm types in the generic, legacy scheme
**What this PR does / why we need it**:
Right now the kubeadm API types are (wrongly from a correctness perspective) installed in the "catch-all" and now legacy `pkg/api/legacyscheme`. Instead, we should use our own, kubeadm-specific `scheme` where our API types are registered. Doing this also cuts one dependency on the internal core API types.
