Follow the new PTI for document build

For compliance with the Project Testing Interface as described in:
[1] https://governance.openstack.org/tc/reference/project-testing-interface.html
[2] http://lists.openstack.org/pipermail/openstack-dev/2017-December/125710.html

[doc/requirements.txt] & [test-requirements.txt]
To support documentation generation in new PTI, project should have
list python dependencies needed for documentation in
doc/requirements.txt which are move from test-requirements.txt

[doc/source/contributor/index.rst] & [setup.cfg]
- Remove [pbr] section in setup.cfg [3], and unrelated lines in
contributor/index.rst
[3] http://lists.openstack.org/pipermail/openstack-dev/2018-March/128594.html
- Add sphinxcontrib.apidoc to replace pbr autodoc

[tox.ini]
--ignore D000: pep8 require sphinx (which move to doc/requirements.txt)
to test doc/source files, however, docs already test the doc/source.
Therefore we can ignore the D000 error code.
