Tyler Goodlet d0f5c7a5e2 Change to `gather_contexts()`, use event for graceful exit 
The api we've made here is actually closer to `asyncio.gather()` but
with opening async context managers instead of funcs. Use another event
to allow for graceful teardown of children on non-cancellation exits
and add a doc string.

Tyler Goodlet 680a841282 Start `trionics` sub-pkg with `async_enter_all()` 
Since it seems we're building out more and more higher level primitives
in order to support certain parallel style actor trees and messaging
patterns (eg. task broadcast channels), we might as well start a new
sub-package for purely `trio` constructions. We hereby dub this
the realm of `trionics` (like electronics but for trios instead of
electrons).

To kick things off, add an `async_enter_all()` concurrent
exit-stack-like context manager API which will concurrently spawn
a sequence of provided async context managers and deliver their ordered
results but with proper support for `trio` cancellation semantics.
The stdlib's `AsyncExitStack` is not compatible with nurseries not
`trio` tasks (which are cancelled) since as task will be suspended on
the stack after push and does not ever hit a checkpoint until the stack
is closed.

Tyler Goodlet 77ec29008d Simplify to soft and hard reap sequences 
This is actually surprisingly easy to grok having gone through a lot of
pain understanding edge cases in the zombie lord dev branch. Basically
we just need to make sure actors are managed in a 2 step reap sequence.
In the "soft" reap phase we wait for the process to terminate on its own
concurrently with (maybe) waiting for its portal's final result (if it's
a `.run_in_actor()`). If this path is cancelled or errors, then we do
a "hard" reap where we timeout and send a signal to the proc to
terminate immediately. The only last remaining trick is to tie in the
root-is-debugger-aware logic to yet again avoid tty clobbers.

Tyler Goodlet bb9d9c74b1 Do immediate remote task cancels 
As for `Actor.cancel()` requests, do the same for
`Actor._cancel_task()` but use `_invoke()` to ensure
correct msg transactions with caller. Don't cancel task
cancels on a cancel-all-tasks operation in attempt at
more determinism.

Tyler Goodlet 10f66e5141 De-noise warnings, add a 'cancel' log level 
Now that we're on our way to a (somewhat) serious beta release I think
it's about time to start de-noising the logging emissions. Since we're
trying out this approach of "stack layer oriented" log levels, I figured
this is a good time to move most of the "warnings" to what they should
be: cancellation monitoring status messages. The level is set to 16
which is just above our "runtime" level but just below the traditional
"info" level. I think this will be a decent approach since usually if
you're confused about why your `tractor` app is behaving unlike you
expect, it's 90% of the time going to be to do with cancellation or
error propagation. This this setup a user can specify the 'cancel' level
and see all the msgs pertaining to both actor and task-in-actor
cancellation mechanics.

Tyler Goodlet d2f0843041 Make custom log levels report the right stack frame 
The stdlib's `logging.LoggingAdapter` doesn't currently pass through
`stacklevel: int` down to its wrapped logger instance. Hack it here
and get our msgs looking like they would if using a built-in level.

Tyler Goodlet c6dc96b08c Add "message transport" structured sub-typing 
In an effort to have some kind of more formal interface around the
transport layer, add a `MsgTransport` protocol type and use with
the channel composition of message streams. Start a little "key map"
of `(<codec>, <protocol>)` to `MsgTransport` types which can be
dynamically loaded. Add a `Channel.from_stream()` constructor thus
cleaning up the mangled logic that was in the constructor based on
inputs. Drop all the "auto reconnect" channel logic for now since
nothing is using it (internally) and it's likely it will need rework
once we bring in a protocol besides TCP.
