Breaking change to Taskcluster Client libraries

[Dustin Mitchell]

Hi friends --

https://github.com/taskcluster/taskcluster-rfcs/pull/135 proposes a
change in how client libraries handle environment variables.

If you use the Python or JS clients, this is a breaking change and
potentially a subtle one - details are in the "compatibility" section.
Please have a look and comment on the PR.

Does this impact how the command line client works?

And how `taskcluster signin` specifically works?

No (but I should address that specifically in the RFC).

Also no. We still support these specific env vars -- they are just
not used by default.

I have moved this to the final-comment phase, as it has internal
agreement. Please speak up soon if this will cause any issues!
Final-comment will last through the weekend and I will begin
implementation on Monday.

I'll be landing this change shortly, releasing both the JS and Python
clients at version 10.0.0 (a big version jump, but for other TC
libraries we have used 10.x as a marker of "rootUrl aware").

The Go library will come along shortly.

Hah, I forgot the JS library is already rootUrl-aware, so the correct
new version is 12.0.0.
