openstack/diskimage-builder - diskimage-builder - OpenDev: Free Software Needs Free Tools

A few differences from the nodepool based testsing:
 * Don't set ELEMENTS_PATH in default_diskimage_environment
 Setting the ELEMENTS_PATH isn't helpful as it generates a number of
 warnings like:
 Element </home/zuul/src/opendev.org/openstack/diskimage-builder/diskimage_builder/elements/block-device-gpt>
 overrides </home/zuul/dib/lib/python3.12/site-packages/diskimage_builder/elements/block-device-gpt>
 We install DIB from the source via the ensure-dib role so the elements
 in site-packages will be installed from source anyway.
 * Do not use opendev opensuse mirror
 We removed this in Ib5d15ce800ff0620187345e1cfec0b7b5d65bee5 which is
 causing the build to fail in nodepool anyway. It's possible this is
 masking another deeper error but let's find out.
 * The gentoo build works in nodepool, but not under devstack. The gentoo
 image being built runs out of space.

We do not need tox_install.sh, pip can handle constraints itself
and install the project correctly. Thus update tox.ini and remove
the now obsolete tools/tox_install.sh file.
This follows https://review.openstack.org/#/c/508061 to remove
tools/tox_install.sh.

Adding constraints support to libraries is slightly more complex than
services as the libraries themselves are listed in upper-constraints.txt
which leads to errors that you can't install a specific version and a
constrained version.
This change adds constraints support by also adding a helper script to
edit the constraints to remove diskimage-builder.

As a first step to OpenStack alignment, get test-requirements.txt in
line with current OpenStack standard practices.

Per http://wiki.openstack.org/ProjectTestingInterface we enable all
of the commands except build_sphinx because we do not have any sphinx
documentation as of yet. Includes babel support though there are no
properly internationalized strings just yet.
