Topically, throughout various (seemingly) console-UX-affecting or benign
spots in the code base; nothing that required more intervention beyond
things superficial. A few spots also include `trio.Nursery` ref renames
(always to something with a `tn` in it) and log-level reductions to
quiet (benign) console noise oriented around issues meant to be solved
long..
Note there's still a couple spots i left with the loose-ify flag because
i haven't fully tested them without using the latest version of
`tractor.trionics.collapse_eg()`, but more then likely they should flip
over fine.
They need to be run with a local private API key and haven't been ported
to latest data apis anyway. It's also a broker most peeps aren't going
to be using any time soon.
Questrade is the default broker backend (for now) so the CI
can run using a practice account token handed down through an
env variable. If we add a cached directory to the build then the token
should remain persistent in the brokers config and will only need to be
updated if something goes wrong.
Also, add a `--confdir` flag for pytest much in the same way as for
the `piker` cli.
