Docker API support and container launch exposure

[raph-luc]

Documentation

configure_container_dict() documentation

To-do (future PRs):

1. Add .env var file for all PyFluent environment variables, and add documentation of how it can be used
2. Are there any scenarios where Docker API/SDK as exposed here does not provide enough functionality, that we should add support for docker compose (https://github.com/docker/compose) in PyFluent? Cloud-native?

Also, see comments below for other changes

Raphael is there an issue that documents what this is for?

Hi Dan, yes, there is an issue associated to this draft PR, it should appear under the "Development" heading in the right sidebar: #1616 (see Sean's reply in particular)

We might want to refactor the launcher code again. The functions here have a tendency to grow. It would be good to keep the functions small so that whole is modular - we want to promote reuse for PyCFX etc. I will create a separate issue.

By the way, with these changes (mainly I believe due to time.sleep -> timeout_loop()), the time taken for all tests to complete appears to have been reduced by approximately 20%, e.g., unit test v232 from 25 min to 20 min, unit test v241 from 14 min to 11 min, disregarding other factors
