New Machine requirement: DockerStatic SUSE BCI image

I need to request a new machine:

- New machine operating system (e.g. linux/windows/macos/solaris/aix): linux
- New machine architecture (e.g. x64/aarch32/arm32/ppc64/ppc64le/sparc): ideally all supported ones - arm64, ppc64le, s390x, amd64
- Provider (leave blank if it does not matter):
- Desired usage: Docker image for SUSE BCI, which is broadly comparable to UBI - images come from registry.suse.com/bci/bci-base as per https://registry.suse.com/bci/bci-base-15sp5/index.html
- Any unusual specification/setup required: Initially it will be likely same as UBI but with `dnf` replaced by `zypper` and `epel` removed from the installed packages in the dockerfile
- How many of them are required: 1 on each architecture

Please explain what this machine is needed for:
We do not have any SLES testing capability on anything other than s390x at the moment. Testing on their BCI v15 images would give us a high degree of confidence that our binaries will work correctly on customer's SLES installations.

Related: https://github.com/adoptium/infrastructure/issues/2689 where SLES15 was added

Start by reviewing related issue #2689 and the SUSE BCI base image details at registry.suse.com/bci/bci-base-15sp5/index.html. Confirm the supported architectures and compare the requested setup with the existing UBI arrangement. Done means one usable SUSE BCI testing machine is available for each requested architecture.
