Python README should include build and test instructions

[jbapple]

The README in the top-level python directory has no build and test instructions. There is a setup.py, but the usage is not fully clear to me. Various combinations of python2, python3, dependencies, command orders, and sudo or not produce a variety of errors.

As an example, sudo python setup.py install warns about setuptools being too old (version 0.0.0, according to the filename), even after pip installing the latest setuptools.

@jbapple I'm going to submit a PR on this, but can you try doing a pip install -e . from the python directory? Note that the iceberg client requires python >= 3.4

Didn't work without sudo. With it:

ERROR: awscli 1.14.19 has requirement botocore==1.8.23, but you'll have botocore 1.12.199 which is incompatible.
ERROR: awscli 1.14.19 has requirement s3transfer<0.2.0,>=0.1.12, but you'll have s3transfer 0.2.1 which is incompatible.

Closing this: Build and test instructions have been added to the refactored python library: https://github.com/apache/iceberg/blob/master/python/README.md
