Update FPB version on PyPi

[Eugene Korekin]

As of now the latest FPB version is 4.0.0, but since this release there was several important bugfixes (for example https://github.com/openstack/fuel-plugins/commit/2d24a9dbe317c0a7308fc9050e302f8cb84e9503).

There was a suggestion from Igor Kalnitsky: "I think we can make a fix "4.0.1" release in order to refer users to install via pip."

Please create this release and ensure that it is uploaoded to PyPi.
