Mitchell Hentges 8f5aad46e5 Bug 1732946: Guard against "pip install" venv conflicts r=ahal
`pip install`'s standard behaviour is to satisfy the new requirement,
even if it conflicts with existing packages. If a conflict _does_
occur, `pip` will simply warn about it after the installation has
already damaged the environment.

By using the `--constraint` feature, we force `pip` to consider
already-installed packages before installing new ones. If a conflict
is detected, an error is raised and `pip` stops without damaging
the environment.

Since we're capturing system packages (when needed) with this feature,
we can now allow virtualenvs that do pip-installations to safely work
with system-using Mach environments.

README

This directory contains common Python code.

The basic rule is that if Python code is cross-module (that's "module" in the
Mozilla meaning - as in "module ownership") and is MPL-compatible, it should
go here.

What should not go here:

* Vendored python modules (use third_party/python instead)
* Python that is not MPL-compatible (see other-licenses/)
* Python that has good reason to remain close to its "owning" (Mozilla)
  module (e.g. it is only being consumed from there).
