Add "excommunicate" debug option
Some debuggers are easier to work with when we do everything in a single process. This debug option caters to that at the expense of being different from what Ansible will actually do to invoke a module. When we document this we should be clear that this shouldn't be used for general purpose debugging and that some modules may show strange "errors" when used with this. Those won't be considered real bugs as it's not how ansible really invokes the modules.
