Merge patch series "Rework requirements.txt files"

Tom Rini <trini@konsulko.com> says:

A challenge we've run in to is making it easier for more people to use
various python tools that we include in the tree. Part of the problem is
that when we have a requirements.txt file, aside from the doc one we
share with the kernel, I created it using "pip freeze". And while this
might have been a best (or at least OK) practice at the time, that's no
longer the case and is why our files have so many things in them. What
this series does is create multiple files, one per project/tool and then
has CI install them as needed. There's a few places here where this
means that we update the requirements as well, but we keep a few big
things where they are currently. This is because updating them
introduces problems of their own and delaing with that would best be a
follow up series. I've put this through GitLab and Azure to make sure
everything is still going fine on both platforms.
