Roman Gorshunov c81a88b963 Embed UML generated diagrams into docs, fix docs build
Remove manual generation of UML diagrams; they will be built by Sphinx
itself.

Require to install PlantUML and Graphviz via bindep in
openstack-tox-docs job; ReadTheDocs service already has both PlantUML
and Graphviz installed for documentation builds.
