The controller must know the ID of the forked child in order to
propagate dependencies to it, so forking+starting the module run cannot
happen entirely on the target, without some additional mechanism to
wait-and-repropagate the deps as they arrive on the target.
Rework things so that init_child() also handles starting the fork parent,
and returns it along with the context's home directory in a single round
trip.
Now master knows the identity of the fork parent, it can directly create
fork children and call run_module_async() in them. This necessitates 2
roundtrips to start an asynchronous task.
This whole thing sucks and entirely needs simplified, but for now things
almost work, so keeping it.
connection.py:
* Expect ContextService to return the entire dict return value of
init_child(). Store the fork_contxt from the return value.
planner.py:
* Rework Planner to store the invocation as an instance attribute, to
simplify method calls.
* Add Planner.get_push_files() and Planner.get_module_deps().
* Add _propagate_deps() which takes a Planner and ensures the deps it
describes are sent to a (non forked or forked) context.
* Move async task logic out of target.py and into invoke() /
_invoke_*().
process.py:
* Services no longer need references to each other. planner.py handles
sending module deps with one extra RPC.
services.py:
* Return "init_child_result" key instead of simple "home_dir" key.
* Get rid of dep propagation from ModuleDepService, it lives in
planner.py now.
target.py:
* Get rid of async task start logic, lives in planner.py now.
