The default bazelrc location is changing. So that we don't break
during the transition, we set up an alias so that bazel versions that
load from the new location are redirected to the old location.
Also add a TODO to move to the new location once bazel 0.18 is
prevalent.
We bumped the version in the Makefile, but I did not understand that we
have to bump the version in the workplace status script. I added a note
in the Makefile, and bumped the version in the script.
