my v5 wishlist:

1. typing/py.typed (finally)
2. oop encapsulate things like waiting and such (finally) (Bug: concurrency causes Premature destruction of containers and networks (e.g. w/pytest-xdist) #567 (comment), Bug: wait_for_logs on DockerCompose container fails #660)
3. how dind works - i think after typing and oop encapsulation this one should be much easier to work on.
4. all of the Network/with_network things
5. standardize compose interface? Using DockerCompose next to dedicated container classes features (like `SqlServerContainer`) #667

smaller things:

1. the logger setup as mentioned in Bug: localnpipe translation not working in v3 #600 (comment)
2. module split / generic module (DbContainer, others)
3. review most function names - lot of unnecessary variety here
