Rename root BUILD to BUILD.bazel, and rename build-tools/ back to build/
**What this PR does / why we need it**: undoes #35453. `build-tools/` was intended to be a temporary workaround until https://github.com/bazelbuild/bazel/issues/552 was fixed, which is has been, as of bazel 0.4.1.
**Which issue this PR fixes**: fixes#38126
FYI @thockin
since this is likely to be rebase hell, my list of actions:
```console
$ git mv BUILD BUILD.bazel
$ git commit -a
$ git mv build-tools/ build/
$ sift -l 'build-tools' | xargs sed -i -e 's:build-tools/:build/:g'
$ git checkout HEAD docs/
$ git commit -a
```

**What this PR does / why we need it**:
It's important, and really hard, to identify kuberentes from kubernetes. As a human being, one's brain tends to auto fix the spelling for you thus when a dev was staring at the log for a good 30-min or so he will start question about his life and belief.
Luckily this is the only place in k/k, it's super important to fix it to avoid future pain.
