switch bootstrap controller to use a client where possible
While looking at https://github.com/kubernetes/kubernetes/issues/37040, I found more places where we can use a normal client instead of a direct to etcd connection.
@wojtek-t you made similar changes in the same controller.

Add kubernetes-anywhere as a new e2e deployment option.
This change adds support for using `kubernetes-anywhere` as a deployment option for hack/e2e.go. This work is toward the larger goal of being able to run e2e tests against `kubeadm` clusters, which `kubernetes-anywhere` supports.
**Release note**:
```release-note
Add kubernetes-anywhere as a new e2e deployment option
```
The configuration in `getConfig()` comes mostly from the defaults in `kubernetes-anywhere`. In the future, we can add more plumbing to override them via CLI flags.

Build vendored copy of go-bindata and use that in go generate step
**What this PR does / why we need it**: as the title says, uses the vendored version of `go-bindata` rather than expecting developers to `go get` it (when building outside docker).
**Which issue this PR fixes**: fixes#34067, partially addresses #36655
**Special notes for your reviewer**: we still call `go generate` far too many times:

add failure check on umount when kubeadm reset, and on service stop
**What this PR does / why we need it**:
before this PR, `umount` will exit with code `123` if `grep` does not match anything
`xargs` has an option:
>-r, --no-run-if-empty
If the standard input does not contain any nonblanks, do not run the command. Normally, the command is run once even if
there is no input. This option is a GNU extension.
1. this PR add `-r` option to `xargs` , so `umount` will not execute and exit with code `0` correctly while `grep` does not match anything.
2. this PR add failure check on umount. for example, if the directory to be umount is busy, a error message will be printed:
>failed to unmount directories in /var/lib/kubelet, umount: /var/lib/kubelet/foo/bar: target is busy
(In some cases useful info about processes that
use the device is found by lsof(8) or fuser(1).)
3. add failure check on kubelet service stop.

change unconfined_t to spc_t
**What this PR does / why we need it**:
When installing kube via kubeadm on a system w/ selinux enabled, it's necessary to disable selinux in order for the etcd and kube-discovery containers to run.
The kube etcd and discovery pods are currently set to unconfined_t in order to avoid disabling selinux, but the correct type for an unconfined container is spc_t. For more information, see http://danwalsh.livejournal.com/2016/10/03/.

Previously, we had no way to stop resync goroutine when ListAndWatch
returned. goroutine leaked every time ListAndWatch returned, for
example, with error. This commit adds another channel to signal that
resync goroutine should exit when ListAndWatch returns.

Fix conditional in log-dump.sh
I think a `-n` was unintentionally changed to a `-z` in #37646, [here](a1bd743118 (commitcomment-20039393)), which caused us to stop collecting master/node logs. This undoes that change.
