Patch piptools to use current environment python

- Fixes #2088, #2234, #1901 - Fully leverage piptools' compile functionality by using constraints in the same `RequirementSet` during resolution - Use `PIP_PYTHON_PATH` for compatibility check to filter out `requires_python` markers - Fix vcs resolution - Update JSON API endpoints - Enhance resolution for editable dependencies - Minor fix for adding packages to pipfiles Signed-off-by: Dan Ryan <[email protected]>
