Write a logging config file and pass it to callbacks

We need to pass a working logging config to zuul_stream and ara so that
alembic migrations don't step on pre-playbook output.

Write a logging config using json, then pass its location in env vars so that
zuul_stream and ara can pick it up and pass it to dictConfig.

In support of this, create a LoggingConfig class so that we don't have
to copy key names and logic between executor.server, zuul_stream and
zuul_json. Since we have one, go ahead and use it for the server logging
config too, providing them with a slightly richer default logging
config for folks who don't provide a logging config file of their own.

The log config processing has to go into zuul.ansible because it's
needed in the bubblewrap and we don't have it in the python path
otherwise.
