Official service-mngr to `tractor.hilevel` move

Such that we maintain that subsys in the actor-runtime repo (with
hopefully an extensive test suite XD).

Port deats,
- rewrite `open_service_mngr()` as a thin wrapper that delegates into
  the new `tractor.hilevel.open_service_mngr()` but with maintenance of
  the `Services` class-singleton for now.
- port `.service._daemon` usage to the new
  `ServiceMngr.start_service_ctx()` a rename from
  `.start_service_task()` which is now likely destined for the soon
  supported `tractor.trionics.TaskMngr` nursery extension.
- ref the new `ServiceMngr.an: ActorNursery` instance var name.

Other,
- always enable the `tractor.pause_from_sync()` support via `greenback`
  whenever `debug_mode` is set at `pikerd` init.

-- 100% federated: your code, your hardware, your data feeds, your broker fills.
-- zero web: low latency, native software that doesn't try to re-invent the OS
-- maximal **privacy**: prevent brokers and mms from knowing your

-- zero clutter: modal, context oriented UIs that echew minimalism, reduce

-- first class parallelism: built from the ground up on next-gen structured concurrency
-  primitives.
-- traders first: broker/exchange/asset-class agnostic
-- systems grounded: real-time financial signal processing that will
-  make any queuing or DSP eng juice their shorts.
-- non-tina UX: sleek, powerful keyboard driven interaction with expected use in tiling wms
-- data collaboration: every process and protocol is multi-host scalable.
-- fight club ready: zero interest in adoption by suits; no corporate friendly license, ever.

-for a development install::
+    piker -l info chart btcusdt.spot.binance xmrusdt.spot.kraken
 
-    git clone git@github.com:pikers/piker.git
-    cd piker
-    virtualenv env

-    pip install -r requirements.txt -e .
+this runs a chart UI (with 1m sampled OHLCV) and shows 2 spot markets from 2 diff cexes
+overlayed on the same graph. Use of `piker` without first starting
+a daemon (`pikerd` - see below) means there is an implicit spawning of the
+multi-actor-runtime (implemented as a `tractor` app).
+
+For additional subsystem feats available through our chart UI see the
+various sub-readmes:
+
+- order control using a mouse-n-keyboard UX B)
+- cross venue market-pair (what most call "symbol") search, select, overlay Bo
+- financial-signal-processing (`piker.fsp`) write-n-reload to sub-chart BO
+- src-asset derivatives scan for anal, like the infamous "max pain" XO

-********************
-bet you weren't expecting this from the foss::
-
-    piker -l info -b kraken -b binance chart btcusdt.binance --pdb
-
-
-this runs the main chart (currently with 1m sampled OHLC) in in debug
-mode and you can practice paper trading using the following
-micro-manual:
-
-``order_mode`` (
-    edge triggered activation by any of the following keys,
-    ``mouse-click`` on y-level to submit at that price
-    ):
-
-    - ``f``/ ``ctl-f`` to stage buy
-    - ``d``/ ``ctl-d`` to stage sell
-    - ``a`` to stage alert
-
-
-``search_mode`` (
-    ``ctl-l`` or ``ctl-space`` to open,
-    ``ctl-c`` or ``ctl-space`` to close
-    ) :
-
-    - begin typing to have symbol search automatically lookup
-      symbols from all loaded backend (broker) providers
-    - arrow keys and mouse click to navigate selection
-    - vi-like ``ctl-[hjkl]`` for navigation
-
-
-you can also configure your position allocation limits from the
-sidepane.
-
-
-run in distributed mode
-***********************
-start the service manager and data feed daemon in the background and
-connect to it::
+spawn a daemon standalone
+*************************
+we call the root actor-process the ``pikerd``. it can be (and is
+recommended normally to be) started separately from the ``piker
+chart`` program::
 
     pikerd -l info --pdb
 
+the daemon does nothing until a ``piker``-client (like ``piker
+chart``) connects and requests some particular sub-system. for
+a connecting chart ``pikerd`` will spawn and manage at least,
 
-connect your chart::
+- a data-feed daemon: ``datad`` which does all the work of comms with
+  the backend provider (in this case the ``binance`` cex).
+- a paper-trading engine instance, ``paperboi.binance``, (if no live
+  account has been configured) which allows for auto/manual order
+  control against the live quote stream.
 
-    piker -l info -b kraken -b binance chart xmrusdt.binance --pdb
+*using* an actor-service (aka micro-daemon) manager which dynamically
+supervises various sub-subsystems-as-services throughout the ``piker``
+runtime-stack.
 
+now you can (implicitly) connect your chart::
 
-enjoy persistent real-time data feeds tied to daemon lifetime. the next
-time you spawn a chart it will load much faster since the data feed has
-been cached and is now always running live in the background until you
-kill ``pikerd``.
+    piker chart btcusdt.spot.binance
+
+since ``pikerd`` was started separately you can now enjoy a persistent
+real-time data stream tied to the daemon-tree's lifetime. i.e. the next
+time you spawn a chart it will obviously not only load much faster
+(since the underlying ``datad.binance`` is left running with its
+in-memory IPC data structures) but also the data-feed and any order
+mgmt states should be persistent until you finally cancel ``pikerd``.

+---------
+the `piker.clearing` subsys is exposed mainly though
+the `piker chart` GUI as a "chart trader" style UX and
+is automatically enabled whenever a chart is opened.
+
+.. ^TODO, more prose here!
+
+the "manual" order control features are exposed via the
+`piker.ui.order_mode` API and can pretty much always be
+used (at least) in simulated-trading mode, aka "paper"-mode, and
+the micro-manual is as follows:
+
+``order_mode`` (
+    edge triggered activation by any of the following keys,
+    ``mouse-click`` on y-level to submit at that price
+    ):
+
+    - ``f``/ ``ctl-f`` to stage buy
+    - ``d``/ ``ctl-d`` to stage sell
+    - ``a`` to stage alert
+
+
+``search_mode`` (
+    ``ctl-l`` or ``ctl-space`` to open,
+    ``ctl-c`` or ``ctl-space`` to close
+    ) :
+
+    - begin typing to have symbol search automatically lookup
+      symbols from all loaded backend (broker) providers
+    - arrow keys and mouse click to navigate selection
+    - vi-like ``ctl-[hjkl]`` for navigation
+
+
+position (pp) mgmt
+------------------
+you can also configure your position allocation limits from the
+sidepane.
