test: allow etcd to run on other ports.
running `make test-integration` with the `ETCD_PORT` option set should
work. Numerous integration test expect the correct URL to be populated
in the `KUBE_INTEGRATION_ETCD_URL` environment variable.
**What this PR does / why we need it**:
This makes the ETCD_PORT option work correctly.

**Special notes for your reviewer**:
I expect nobody is using the ETCD_PORT option, but I noticed that it is broken.

First version of this was only standalone, now the code is being
vendored by anyone who wants to use it. So the standalone binary and
container are no longer useful.

Exit gce kube-up.sh early if openssl is LibreSSL
**What this PR does / why we need it**:
macOS has an openssl binary, but it's actually LibreSSL, which doesn't play well with the easyrsa script that cluster/gce/util.sh uses to generate certs
Instead of waiting until we generate certs to discover easyrsa doesn't work, consider openssl a prereq for gce, and include a check for the version string starting with OpenSSL
Also, mirror kube-up.sh's "... calling" output in kube-down.sh

We are not saving the etcd logs and just redirecting the output
to /dev/null. In this change, we set ETCD_LOGFILE to the same
directory where we log other kube relates processes.

Update all script shebangs to use /usr/bin/env interpreter instead of /bin/interpreter
This is required to support systems where bash doesn't reside in /bin (such as NixOS, or the *BSD family) and allow users to specify a different interpreter version through $PATH manipulation.

Use /usr/bin/env in all script shebangs to increase portability.

Bump minimum required go version to 1.10.1

Build cleanup with go 1.10
Simplify our build/test scripts now that go 1.10 is in play. It has caching that seems to actually work.
**Release note**:
```release-note
NONE
```
As of go 1.10, we do not need to explicitly build the stdlib for static
any more. That happens automatically. Timing tests show no discernible
difference between a `go install` with and without it.
Also use 'static' suffix instead of 'cgo'.

Vendor gazelle and kazel
Rather that relying on upstream git repos that can break, vendor it all. These are NOT head of tree, respectively - they are some backrev forms that were previously being used.

In nested virutalized environments, the 1 second max-time is too
low. Just bumping up WAIT_FOR_URL_API_SERVER does not work unless
we bump up the max-time too. Let us just make it configurable like
so folks can customize to their environment.

Bump to etcd 3.1.12 to pick up critical fix
etcd [3.1.12](https://github.com/coreos/etcd/releases/tag/v3.1.12) (as well as 3.2.17 and 3.3.2) was released yesterday to fix a bug critical to kubernetes:
Fix [mvcc "unsynced" watcher restore operation](https://github.com/coreos/etcd/pull/9297).
- "unsynced" watcher is watcher that needs to be in sync with events that have happened.
- That is, "unsynced" watcher is the slow watcher that was requested on old revision.
- "unsynced" watcher restore operation was not correctly populating its underlying watcher group.
- Which possibly causes [missing events from "unsynced" watchers](https://github.com/coreos/etcd/issues/9086).
This will be backported to 1.9 as well.
Release note:
```release-note
Upgrade the default etcd server version to 3.1.12 to pick up critical etcd "mvcc "unsynced" watcher restore operation" fix.
```
