idea: job that blocks until scf is running, and then performs some cf cli steps

[drnic]

When I bootstrap --scf there are sometimes additional admin steps to perform once scf is finally running. https://github.com/starkandwayne/update-all-cf-buildpacks is an example -- it blocks via an init container until SCF is running.

For example, I'd like to install service brokers once SCF is running.
