Tyler Goodlet b8b76a32a6 Harden container cancel-and-wait supervisor loop
This should hopefully make teardown more reliable and includes better
logic to fail over to a hard kill path after a 3 second timeout waiting
for the instance to complete using the `docker-py` wait API. Also
generalize the supervisor teardown loop by allowing the container config
endpoint to return 2 msgs to expect:
- a startup message that can be read from the container's internal
  process logging that indicates it is fully up and ready.
- a teardown msg that can be polled for that indicates the container has
  gracefully terminated after a cancellation request which is passed to
  our container wrappers `.cancel()` method.

Make the marketstore config endpoint return the 2 messages we previously
had hard coded and use this new api.

Tyler Goodlet 1dca7766d2 Add notes about how to do mkts "trimming"
Which is basically just "deleting" rows from a column series.
You can only use the trim command from the `.cmd` cli and only with a so
called `LocalClient` currently; it's also sketchy af and caused
a machine to hang due to mem usage..

Ideally we can patch in this functionality for use by the rpc api
and have it not hang like this XD

Tyler Goodlet b910eceb3b Add `ShmArray.ustruct()`: return an unstructured array copy
We return a copy (since since a view doesn't seem to work..) of the
(field filtered) shm array contents which is the same index-length as
the source data.

Further, fence off the resource tracker disable-hack into a helper
routine.

Tyler Goodlet 1657f51edc Manually fetch missing out-of-order history frames
It seems once in a while a frame can get missed or dropped (at least
with binance?) so in those cases, when the request erlangs is already at
max, we just manually request the missing frame and presume things will
work out XD

Further, discard out of order frames that are "from the future" that
somehow end up in the async queue once in a while? Not sure why this
happens but it seems thus far just discarding them is nbd.

Tyler Goodlet 26fddae3c0 Fix earliest frame-end not-yet-pushed check
Bleh/🤦, the ``end_dt`` in scope is not the "earliest" frame's
`end_dt` in the async response queue.. Parse the queue's latest epoch
and use **that** to compare to the last last pushed datetime index..

Add more detailed logging to help debug any (un)expected datetime index
gaps.
