feat(gerrit): update CL when buildKite build is finished

buildKite can call specific hooks at various stages ([1]). We add a hook
to run after each command. For now we only care if the label of the
command is `:hammer:', since this is what we've defined for our pipeline.

After a successful build, the agent will post a review with +1 if it's a
success, or -1 if the build results in failure.
