Re-enable node problem detector by default
Re-enable node problem detector started in gce cluster by default.
For now, in the master node, the node problem detector will be started and do nothing (see https://github.com/kubernetes/node-problem-detector/pull/13).
But in fact, in my test cluster, the master has no extra cpu to run the node problem detector, so node problem detector is started on all nodes except master, which is what we want but not expected...

/cc @andyzheng0831 for the gci script change.

This change recovers some of the side effects of
https://github.com/kubernetes/kubernetes/pull/26197, i.e., keeps the defaults of
`NODE_IMAGE` and `NODE_IMAGE_PROJECT` to `MASTER_IMAGE` and
`MASTER_IMAGE_PROJECT`, for backward compatibility. Although it keeps
`OS_DISTRIBUTION` defaulting to `gci`, the default settings of these vars are
moved to `cluster/gce/util.sh` and conditioned on `OS_DISTRIBUTION==gci`.

Add node problem detector as an addon pod.
```release-note
Introduce a new add-on pod NodeProblemDetector.
NodeProblemDetector is a DaemonSet running on each node, monitoring node health and reporting
node problems as NodeCondition and Event. Currently it already supports kernel log monitoring, and
will support more problem detection in the future. It is enabled by default on gce now.
```
This PR enables NodeProblemDetector as an add-on pod.

Salt configuration for the new Cluster Autoscaler for GCE
Adds support for cloud autoscaler from contrib/cloud-autoscaler in kube-up.sh GCE script.
cc: @fgrzadkowski @piosz
Allow the gcr.io/google_containers registry to be overridden
regionally by just blasting a new KUBE_ADDON_REGISTRY out. Instead of
adding every addon to Salt and asking all of the other consumers
(Trusty, Juju, Mesos, etc) to change, just script the sed ourselves.
This is probably the 9th grossest thing I've ever done, but it works
well, and it works quickly. I kind of wish it didn't.
* In kube-up.sh, create a staging bucket with a location nearest the
zone being created. If new variable RELEASE_REGION_FALLBACK is set
(default false), create multiple buckets and stage to fallback
URLs. (In open source, this path is primarily for testing.)
* In configure-vm.sh, split the URL env variables by comma (if any
extra are present) and retry on the fallback URLs. Also factor the
hash checking into this path rather than outside, since a corrupt
release in a particular geo can be retried in a different geo.
* Remove the local already-staged .tar.gz checks. They've caused
several issues along the way, and with this code path become virtually
unmaintainable. (I could add a sentinel for each bucket it's possibly
staged to, but ew.)
