Mitchell Hentges a37e7812d4 Bug 1748737: Bump attrs to be compatible with mochitest r=ahal
A bunch of modern packages (`pytest`, `twisted`, `automat`) all need
`attrs==19.2.0` (or newer).
We _could_ bump `attrs` all the way to the modern `21.4.0` version, but
I'd like to defer that upgrade risk, since there's a
lot of backwards-incompatible changes and deprecations. So, lightly bump
it to `19.2.0`.

As part of bumping it, `pytest` is no longer compatible.
The earliest candidate that seems to be compatible is `pytest` 4.6.6,
which boasts in its release notes that it's resolved some deprecation
warnings against `attrs>=19.2.0`.

Once `pytest` was bumped, it needed a newer version of `pluggy`, which
itself has dependencies.
Since we're using hashes in `tox_requirements.txt`, all dependencies
needed to be hashed as well.
