* Setuptools v54.1.0 introduces a warning that the use of dash-separated
options in 'setup.cfg' will not be supported in a future version .
Get ahead of the issue by replacing the dashes with underscores.Without
this, we see 'UserWarning' messages.
* Replace .testr.conf by .stestr.conf for migration and update
.gitignore and test-requirements.txt file accordingly
* Use py3 as the default runtime for tox
* Add a new job, openstack-cover-jobs, to run the coverage in Zuul
This patch enables building .pdf documentation using new 'pdf-docs'
tox environment. The newly created tox environment creates latex
source codes using sphinx-build and then builds the pdf
documentation using make.
In preparation for python 3 support switch to newer sphinx version.
This requires openstackdocstheme.
Remove install_command, this is the default.
Update hacking version to be compatible with python 3, fix warnings
from new pep8.
We want to default to running all tox environments under python 3, so
set the basepython value in each environment.
We do not want to specify a minor version number, because we do not
want to have to update the file every time we upgrade python.
We do not want to set the override once in testenv, because that
breaks the more specific versions used in default environments like
py35 and py36.
