Check test functionality in image mode.

testing-farm request --context deployment-mode=image --context distro=rhel-9.7 OR 10 --compose RHEL-9.7.0-image-mode OR 10 --arch x86_64 --git-url https://pkgs.devel.redhat.com/git/tests/<package> --git-ref master

Also as a part of this task, consider to create or extend test coverage to be sufficient for image mode.

Almost correct request:

testing-farm request --context deployment-mode=image --context distro=rhel-9 --plan bind9.18  --compose RHEL-9.8.0-image-mode --arch x86_64 --git-url https://gitlab.com/redhat/centos-stream/tests/bind --plan-filter 'name:/plans/bind9.18/.*' --test-type fmf --git-ref main --redhat-brew-build 69664124
