The .pdf documentation could not be build without errors because the
source code of the documentation contained errors. In addition, there
were other problems:
- The readme section of the documentation was in .md format
instead of .rst format. As a result, the created documentation did
not look good.
- The .html documentation used deprecated oslosphinx theme instead
of openstackdocstheme.
This patch fixes the above-mentioned problems and makes sure that
the documentation is generated properly.
Also, this patch updates nodejs4-docs to nodejs10-docs because the
nodejs4-docs was using deprecated nodejs-npm-run-docs job [1].

readme.rst includes a README.rst file that does not exist - we have a
README.md but cannot include it here. Thus remove the readme.rst file.
