Remove intersphinx from the docs build as it triggers network calls that
occasionally fail, and we don't really use intersphinx (links other
sphinx documents out on the internet)
This also removes the requirement for internet access during docs build.
This causes docs jobs to fail because we error out on warnings.

Related-Bug: #1368910
Having the sphinx theme in the same namespace package
as the production code has been causing issues with
devstack installations. The solution settled on was
to rename oslo.sphinx to oslosphinx because oslo.sphinx
is not a "production" library.
See the linked bug report for more background details.

Use the new oslo.sphinx version of the OpenStack doc
theme instead of copying it into this repo.
blueprint oslo.sphinx
