Core installation fails with NameError: global name 'get_installed_distributions' is not defined

According to this https://github.com/pypa/pip/issues/5243 you are no longer allowed to us get_installed_distributions from PIP. Instead, you are meant to use working_set from pkg_resources. I've changed the code to use this and works fine. However, I'm not a developer, so not sure the code is 100% correct. Patch follows:

Ran into this same issue. Used the changes above and commented out the git section of the playbook and successfully installed minemeld. Thanks!

Thanks @goniomdq. We just merged a fix for this (PaloAltoNetworks/minemeld-core#300). Could you try?
