This implements the first edition of Connection Delegation, where
delegating connection establishment is initially single-threaded.
ansible_mitogen/strategy.py:
ansible_mitogen/plugins/connection/*:
Begin splitting connection.Connection into subclasses, exposing them
directly as "mitogen_ssh", "mitogen_local", etc. connection types.
This is far from removing strategy.py, but it's a tiny start.
ansible_mitogen/connection.py:
* config_from_play_context() and config_from_host_vars() build up a
huge dictionary containing either more or less PlayContext contents,
or our best attempt at reconstructing a host's connection config
from its hostvars, where that config is not the current
WorkerProcess target.
They both produce the same format with the same keys, allowing
remaining code to have a single input format.
These dicts contain fields named after how Ansible refers to them,
e.g. "sudo_exe".
* _config_from_via() parses a basic connection specification like
"username@inventory_name" into one of the aforementioned dicts.
* _stack_from_config() produces a list of dicts describing the order
in which (Mitogen) connections should be established, such that each
element is proxied via= the previous element. The dicts produced by
this function use Mitogen keyword arguments, the former di.
These dicts contain fields named after how Mitogen refers to them,
e.g. "sudo_path".
* Pass the stack to ContextService, which is responsible for actual
setup of the full chain.
ansible_mitogen/services.py:
Teach get() to walk the supplied stack, establishing each connection
in turn, creating refounts for it before continuing.
TODO: refcounting is broken in a variety of cases.
