ansible: enable forking when requested and for async jobs. Closes #105. References #155. mitogen/service.py: Refactor services to support individually exposed methods with different security policies for each method. - @mitogen.service.expose() to expose a method and set its policy - @mitogen.service.arg_spec() to validate input. - Require basic service message format to be a tuple of `(method, kwargs)`, where kwargs is always a dict. - Update DeduplicatingService to match the new scheme. ansible_mitogen/connection.py: - Rename 'method' to 'method_name' to disambiguate it from the service.call()'s method= argument. ansible_mitogen/planner.py: - Generate an ID for every job, sync or not, and fetch job results from JobResultService rather than via the initiating function call's return value. - Planner subclasses now get to select whether their Runner should run in a forked process. The base implementation requests this if the 'mitogen_isolation_mode=fork' task variable is present. ansible_mitogen/runner.py: Teach runners to deliver their result via JobResultService executing in their indirect parent mux process. ansible_mitogen/plugins/actions/mitogen_async_status.py: Split the implementation up into methods, and more compatibly emulate Ansible's existing output. ansible_mitogen/process.py: Mux processes now host JobResultService. ansible_mitogen/services.py: Update existing services to the new mitogen.service scheme, and implement JobResultService: * listen() method for synchronous jobs. planner.invoke() registers a Sender with the service prior to invoking the job, then sleeps waiting for the service to write the job result to the corresponding Receiver. * Non-blocking get() method for implementing mitogen_async_status action. * Child-accessible push() method for delivering task results. ansible_mitogen/target.py: New helpers for spawning a virginal subprocess on startup, from which asynchronous and mitogen_task_isolation=fork jobs are forked. Necessary to avoid a task inheriting potentially polluted/monkey-patched parent environment, since remaining jobs continue to run in the original child process. docs/ansible.rst: Add/merge/remove some behaviours/risks. tests/ansible/integration: New tests for forking/async.
