Use openstackdocstheme over oslosphinx

This commit is part of general doc-migration effort. It replaces
oslosphinx with openstackdocstheme and marks docs warnings to be treated
as errors.

Kuryr projects do not seem to have any docs in the openstack-manuals, so
there are no docs we need to pull from that repo.
However being the official project kuryr would benefit from unifying
its docs with the rest of openstack projects as well as using
openstackdocstheme, theme intended for official projects
https://docs.openstack.org/openstackdocstheme/latest/

See https://specs.openstack.org/openstack/docs-specs/specs/pike/os-manuals-migration.html
and https://etherpad.openstack.org/p/doc-migration-tracking for more
