Ian Wienand 18215274d8 pip-and-virtualenv : deprecate source for CentOS 8, new variables
As described inline, deprecate the "source" install for CentOS 8.
Overwriting the packaged tools has long been a pain-point in our
images, and the best outcome is just not to play the game [1].

However, the landscape remains complicated.  For example, RHEL/CentOS
8 introduces the separate "platform-python" binary, which seems like
the right tool to install platform tools like "glean" (simple-init)
with.  However, platform-python doesn't have virtualenv (only the
inbuilt venv).

So that every element doesn't have to hard-code in workarounds for
these various layouts, create two new variables DIB_PYTHON_PIP and
DIB_PYTHON_VIRTUALENV to just "do the right thing".  If you need is
"install a pip package" or "create a virtualenv" this should work on
all the platforms we support.  If you know more specifically what you
want (e.g. must be a python3 virtualenv) then nothing stops elements
calling that directly (e.g. python3 -m virtualenv create); these are
just helper wrappers for base elements that need to be broadly
compatible.
