This option causes the installation of the "glance" command to fail in
the functional tests. We have removed it from glance and glance_store in
the past to improve compatibility with tox>=4.0, so let us do the same
in glanceclient.

The argparse module automatically replaces '-' characters with '_'
characters when converting an option string to an attribute:

«For optional argument actions, the value of dest is normally inferred
from the option strings. ArgumentParser generates the value of dest by
taking the first long option string and stripping away the initial --
string. If no long option strings were supplied, dest will be derived
from the first short option string by stripping the initial - character.
Any internal - characters will be converted to _ characters to make sure
the string is a valid attribute name.»[1]

This means that the value of the "--remote-region" option of the
"image-import" command will be available as "args.remote_region";
"remote-region" would not be a valid attribute anyway.

We make sure to retrieve the proper value for the following
options: --remote-region, --remote-image-id and
--remote-service-interface.

Partial-Bug: #2012442

Add file to the reno documentation build to show release notes for
stable/2023.1.

Use pbr instruction to increment the minor version number
automatically so that master versions are higher than the versions on
stable/2023.1.

First, fix test_help(). A commit[1], which first appeared in Python
3.10, changes the output of the help feature of argparse. Options used
to be in a section named "Optional arguments:", and they are now in a
section named "Options:".

Second, tox 4 changes the behaviour of tox, and
{toxinidir}/requirements.txt is no longer installed automagically in the
docs virtual environment. This causes autodoc to fail on some imports.
We explicitely add {toxinidir}/requirements.txt to the list of
dependencies to fix this issue.

These issues should be fixed in separate patches, but since they both
block the CI, they depend on each other.
