[Proposal] Creation of a `mozilla-taskgraph` module

Hey everyone,

Release Engineering has an open RFC to create a mozilla-taskgraph module to house the Mozilla-specific logic that currently resides in Taskgraph. If this is of interest to you, the RFC is open to comment through the end of the week:
https://github.com/mozilla-releng/releng-rfcs/pull/41

Thanks!
Andrew
