the fixtures from chatmaild and cmdeploy test plugins were clashing,
and the "rpc" fixture was shadowed by deltachat-rpc-client.
We could change the way plugins load but it's also useful to have
disambiguated fixture names as we are often working across the code bases.
also removes a few unused historic fluff.
turns out Python has the nice https://pypi.org/project/lupa/
that allows us to quite easily test dovecot LUA parts
without figuring out errors on deploy.
* cleanup: remove CFFI deltachat bindings usage, and consolidate test support with rpc-bindings
major simplification: all chatmail fixtures used in the test are now created inside the cmdeploy plugin,
and do not inherit anything from other fixture machineries, let alone the legacy deltachat CFFI ones.
also fix that pytest report headers show correct chatmail domains under test
* drastically reduce round-trips for dns checks, and do it during 'run' and 'dns' sub commands
* provide progress-dots for dns checks and "--verbose" for seeing what is executed remotely
* introduce ssh-mediated remote python function execution mechanism
