Bug 1045730 - Add task-specific configuration to Runner

This should be what we want.

Bonus: removed packaging/deployment from README as that was done weeks ago! (also hey look emoji in git commit messages!)
then you can call this task_config

you could have get_task_config return an empty dict if there's no specific config. then you could write the loop as something like:

for k, v in default_config:
    if k not task_config:
       task_config[k] = v

I'm not sure that we have to worry about the presence of other keys.
