Option to set the default distribution algorithm

See original GitHub issue

Hi, I have the following scenario:

I have some tests that need to be run in the same worker due to the fact they use a shared object (I know it’s not very idiomatic for unit tests, but it is really the simpler way to check what I need to check)
I saw the --dist loadgroup option, but unfortunately it is not the default, so I should remember to specify every time the command line option
I can’t add it to the addopts setting since it errors if I don’t specify either -n or -tx, and I want to be able to choose to run the tests the standard way too.

What could work for me is a setting to set the default algorithm to use when --dist is not specified, so that:

if I run pytest standalone, it doesn’t run in parallel
if I run pytest -n auto, it uses the algorithm specified in the setting
if I run pytest -n auto --dist loadfile, it overrides the setting with the loadfile algorithm.

It can be implemented since we had to do it by using pytest hooks, but it’s quite messy since you have to dig deep inside how the workers read the options
