Depreciated pip option PIP_DOWNLOAD_CACHE removal

Browse Source 
Fix warning:
DEPRECATION: --download-cache has been deprecated and will be removed in the
future. Pip now automatically uses and configures its cache.

1. Since version 6.0 (2014-12-22) pip has deprecated PIP_DOWNLOAD_CACHE
   and now automatically uses and configures its cache.
   Default new location is $HOME/.cache/pip.
2. pip gets upgraded to the latest version in tools/install_pip.sh
   but if pip version<6, exit with error: "Currently installed pip version
   ${pip_version} does not meet meet minimum requirements"
