jenkins: Allow configuration of release bucket
This allows others to leverage the existing E2E code to test some
patched kube binary by simply overriding the bucket and reusing many of
the existing scripts

Trusty: Regional release .tar.gz support
@zmerlynn and @roberthbailey please review it. This change is to support the feature added in PR #22234. The entire logic is pretty much the same as in #22234, with only few minor changes in implementation.
I had manually run e2e tests with "export RELEASE_REGION_FALLBACK=true" on two clusters: (1) Trusty on master nodes on ContainerVM; (2) Master and nodes all on trusty. All tests are green. I don't figure out a way to simulate regional fallback. But I did test the function download_or_bust() out-of-box.
cc/ @wonderfly @dchen1107 @fabioy FYI.
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.)
