doorstop/core/builder: .doorstop.skip-all allows skipping subdirs entirely

[stanislaw]

This feature is inspired by another pending PR: #431.

While I need this feature to implement LIT-based tests so that they do not collide with the existing test suite, I think this feature can be useful in general because it makes it possible to skip useless directories recursively.

Also I noticed that Doorstop does os.walk through all of the .git, .venv, .cache and other directories which means it does a lot of useless work. I have added a filter for a at least .git folder to not be included into the os.walk traverse plan.

Thanks for responding quickly! I need to write the unit tests to catch these coverage bits. Wanted to open this as a RFC first so it is good to have your approval in general!

@jacebrowning I have written what I think are good tests but the coveralls still says I am decreasing the code coverage.

I am pretty sure it is due to the fact that the number of lines has increased, as @sebhub explained here: #425 (comment).

Any recommendations on how I should proceed?

I could grab any file with the lowest code coverage and open a separate PR to increase the total number. But before I do that I would like to understand where the setting for this check is located: is it a fixed number or the rule is "no less than" that the current value?

@stanislaw I just changed the coverage decrease threadshold to 0.1%, which is a setting on the Coveralls site:

I think the tests here are sufficient.

@jacebrowning it has passed, thanks for the correction. Please proceed with a merge if everything is ok.
