Function dbcrossbarlib::tokio_glue::run_futures_with_runtime

pub fn run_futures_with_runtime(
    cmd_future: BoxFuture<()>, 
    worker_future: BoxFuture<()>
) -> Result<()>

Create a new tokio runtime and use it to run cmd_future (which carries out whatever task we want to perform), and worker_future (which should have been created by Context::create or Context::create_for_test).

Return when at least one future has failed, or both futures have completed successfully.

This can be safely used from within a test, but it may only be called from a synchronous context.

If this hangs, make sure all Context values are getting dropped once the work is done.
