Vendor bleach and html5lib in pip package

TensorBoard uses bleach, which depends on html5lib, which made a big breaking
change at some point in the past. Since upgrading these dependencies is not
possible, we'll shade them under the `tensorboard._vendor` namespace, which is
magically created by our build_pip_package script, which was rewritten, to
support smoke testing and dash.

The new process for building the TensorBoard pip package is:

```sh
rm -rf /tmp/tensorboard
bazel run //tensorboard/pip_package:build_pip_package
pip install -U /tmp/tensorboard/*py2*.pip
```

Fixes tensorflow/tensorflow#16424
Fixes #427
Fixes #588
Closes #607
Could help #748
