test: use docker

[danilshvalov]

Possible testing implementation provided by docker. Refers to #413

[cseickel]

While we no longer need it to deal with the changes in #413, it is nice to have a minimal docker container as an optional tool. I think I'll also add a version for a stable release at some point.
