Use abi3 wheels instead of separate python 3.x versions

[alippai]

Newer pip versions supports abi3 wheels, which means there is no need for separate wheels for every python version, but a stable, shared abi can be used. I think it would help the maintenance if this limited abi fits the ray projects needs.
