[WIP] AWS compatibility for federation cluster and e2e
I've been testing this and have reached a point where the e2e tests run, and some test failures are popping up which are not overtly related to AWS specific things.

\cc @quinton-hoole @madhusudancs for advice. Should I investigate further?
this is the same criteria that is currently applied for ascertaining ownership other resources ( eg: security groups, which are also deleted in a similar fashion)
We are now respecting existing cluster namespace isolation rules.

Ubuntu: download client and server tarballs instead of mondo-tarball
Part of #28629 / #28435.
This should be functionally the same, except that you will download ~1/3 the bytes.

Fix upgrade.sh image setup
The original fix (#33147) sourced the correct `node-helper.sh` but set
`node_os_distribution` instead of `NODE_OS_DISTRIBUTION`. The
`set-node-image` function is imported indirectly via `source
"${KUBE_ROOT}/cluster/kube-util.sh"`, which in turn (in the GCE case)
sources `cluster/gce/util.sh`. Since the `set-node-image` function
relies on the `NODE_OS_DISTRIBUTION` variable, the original fix
did not have the entire intended effect.
I have confirmed that cherry-picking #33147 into the `release-1.4`
branch and layering this commit on top of it make for a successful
upgrade from a GCI based K8s 1.3 cluster to a GCI based K8s 1.4 cluster.
**NOTE:** This, along with #33147, should be cherry-picked into the `release-1.4` branch.

log-dump.sh: Add a LOG_DUMP_USE_KUBECTL mode, refactor
**What this PR does / why we need it**: This refactors log-dump.sh so that it can optionally just use `"kubectl get node"` output, for dumping logs off a cluster that was brought up using something other than kube-up.sh (e.g. kops or kubeadm).
Note that for obvious reasons, if the cluster is fried, it'll probably fail to hit the apiserver and all bets are off, but for the 95% case where you're debugging tests, this is good. To cover the remaining 5%, you could actually squirrel away the relevant external IPs after the e2e.go:Up stage (because we better be able to hit the apiserver then) and fetch them from cache later.
**Special notes for your reviewer**: Sorry for so many changes. :)

Juju automated charm testing shouldn't bootstrap
**What this PR does / why we need it**:
**Special notes for your reviewer**: This controls the tooling around our test automation. This is a low impact change to the k8s codebase, that will have a big impact on our CI infrastructure.
**Release note**:
```release-note
release-note-none
```
Juju bootstrapping is an act of cost. This should be an explicit action
by the tooling surrounding bundle-tester when testing a charm. Setting
bootstrap:false will allow us to get faster feedback at lower cost when
running the kubernetes charm under ci.

Create a get-kube-binaries script to download client/server tarballs
**What this PR does / why we need it**:
One step towards removing all server and client binary tarballs from the kubernetes.tar.gz release tarball.
If someone uses `cluster/get-kube.sh` (or https://get.k8s.io, which needs to be synced), this will automatically download the necessary client and server tarballs as part of the flow, though as of right now this will largely be a no-op. (When we remove the client/server binaries, it will have more of an effect.)
I've opted to put this script inside the release tarball (rather than in get-kube.sh), since each release probably has a better idea which platforms/architectures/etc it supports.
Further improvements would probably include omitting downloading the server tarball entirely unless needed, but this seems like a reasonable first step.
This also fixes some errors in get-kube.sh, and remove client architectures we don't officially support.
**Which issue this PR fixes** *(optional, in `fixes #<issue number>(, #<issue_number>, ...)` format, will close that issue when PR gets merged)*: fixes #
x-ref #28629 and #28435
**Special notes for your reviewer**
Assigning to Tim semi-arbitrarily for now, but please reassign as you feel appropriate.
**Release note**:
We probably don't need a release note yet. We'll definitely want one when we remove the server and client binaries.

Speed up dockerized builds
This PR speeds up dockerized builds. First, we make sure that we are as incremental as possible. The bigger change is that now we use rsync to move sources into the container and get data back out.
To do yet:
* [x] Add a random password to rsync. This is 128bit MD4, but it is better than nothing.
* [x] Lock down rsync to only come from the host.
* [x] Deal with remote docker engines -- this should be necessary for docker-machine on the mac.
* [x] Allow users to specify the port for the rsync daemon. Perhaps randomize this or let docker pick an ephemeral port and detect the port?
* [x] Copy back generated files so that users can check them in. This is done for `zz_generated.*` files generated by `make generated_files`
* [x] This should include generated proto files so that we can remove the hack-o-rama that is `hack/hack/update-*-dockerized.sh`
* [x] Start "versioning" the build container and the data container so that the CI system doesn't have to be manually kicked.
* [x] Get some benchmarks to qualify how much faster.
This replaces #28518 and is related to #30600.

Bump glbc version to 0.8.0
Picks up k8s.io godeps for v1.4 thereby fixing an int overflow bug in the upstream delayed-workqueue pkg. Without this the controller spams logs with retries in the "soft error" case, which is easy to come by when users eg: create ingresses that point to non-exist services.
Should go into 1.4.1, because 1.4.0 is pretty much out at this point.
