Initial spike on bazel compilation

Install the latest version of bazel, and try building

`bazel build java/client/src/org/openqa/selenium/remote`

If everything goes according to plan, this will have
built the remote java bindings. Woot.

The design principles for the BUILD files are fairly
simple:

* Keep It Stupidly Simple (aim for one target per file)
* Only use public visibility for rules that will
  generate a publicly downloadable artifect (eg. a
  maven jar, a ruby gem, etc)
* Minimal visibility for everything else
* Each rule should only be reachable from one publicly
  visible rule (allowing us to generate deployment
  descriptors when we get there)

Problems to address before we can consider switching to
bazel for all builds:

* The publishing story is a mess. Notably, Buck made it
  easy to push to maven central. Bazel's a mess for this.
* Generating java 9 module information. This is probably
  just a case of copying what we did for Buck.
* How to properly integrate into the rest of the build,
  in particular for those languages we didn't properly
  cover off with Buck (though that's not a blocker ---
  feature parity with what we have is)
