Remove config values from master god config

This commit removes the config values from the master god config file.
This is because they can be set in any of the god config files rendered
for a particular app.
Source default rvm if it exists

In order to ensure that god is run from the default rvm environment,
this commit updates the runit template for god. It sources the default
rvm environment if it exists and runs the god command within that
context.
