openstack-doc-test has been removed from openstack-doc-tools in release
1.0.0. Remove it's usage from this project.
Also, remove doc-test.conf file, it was used by openstack-doc-tools.
Remove checkniceness and checksyntax targets, they are unused and not
needed. Merge doc8 check into pep8 and doc environments (note that
OpenStack CI does not use doc environment, so add it to pep8 as well) as
is custom for lint like jobs. Fix requirements to follow best practices.
Add doc8 to test-requirements to document its usage properly, add sphinx
there as well.
