Making thrift, pyhive and tableschema as extra_requires (#6696)

* Making thrift, pyhive and tableschema as extra_requires

Looking at the dependency tree for license related questions, I noticed
that tableschema had a huge tree, and only people running Hive really
need it. Making this as well as pyhive and thrift optional.

Also bumping some python dependencies

* Run pip-compile

* Removing refs to past.builtins (from future lib)

* Add thrift
