Updates to prepare for PyPI releases.

[cbrainerd]

A new PyPI readme template is added

This template is rendered during the build process so that the correct package name is displayed in installation instructions and example code. After rendering it will be displayed on PyPI. See examples on test PyPI: https://testpypi.python.org/pypi/isi-sdk-8-0 https://testpypi.python.org/pypi/isi-sdk-7-2

Updates to the hard coded swagger json

Fields in the hardcoded portions of swagger json have been updated:

• Description is updated to make sense in the context of a PyPI package page
• License URL points to the license on the isilon_sdk repo
• Terms and conditions points to emc code governance and code of conduct page

  Version is auto-populated in the swagger json

• OneFS version info is automatically populated into the swagger json API version field

  Python setup.py custom codegen templates

• Custom templates are added for the setup.py so that PyPI docs can be rendered with exact package name instead of relying on notes in the readme such as

isi_sdk_7_2 or isi_sdk_8_0 depending on which is installed
