Add licenses to Python images

[adriangonz]

Related to #1360

Changelog

• Add tox environment to generate the licensing info using pip-licenses
• Add generated licenses/license.txt and licenses/dep.csv to repo
• Copy licenses explicitly on non-local s2i images

Notes

The pip-licenses tool generates the list of deps from the installed packages. To avoid a "dirty" local virtualenv (and pulling in licenses not required by seldon-core) I've added a tox env which generates the list.
