update to torch 1.11, python 3.10

[d4l3k]

Now that torch 1.11 is released we should update to it. Also adds python 3.10 support to the unit tests now that torch supports it.

Ray doesn't support Python 3.10 so we exclude it from dev-requirements on 3.10. ray-project/ray#21221

Test plan:

CI

torchx/runtime/container/build.sh
