ci - partition job failures

[Julia Kreger]

The partition jobs can fail in odd ways, specifically erroring suggesting /bin/sh is missing in the image:

Mar 14 19:07:16.681311 np0037067775 nova-compute[104237]: Exit code: 127

We believe this is rooted in the way the job's base image is actually created by booting the cirros kernel and ramdisk, and creating a partition image from the resulting disk contents, as cirros's disk image is actually blank by default, and it is the only way to "capture" the contents. The current believe is that this is something to do with that process resulting in /bin/sh missing, which causes the CI job to fail.

    Tempest test with only wholedisk for some jobs

    Changing the ironic-tempest-uefi-redfish-vmedia and
    ironic-tempest-ovn-uefi-ipmi-pxe jobs to only run
    tempest test_baremetal_server_ops_wholedisk_image.

    We saw failures on the partition tests for this jobs.

This should largely be resolved by https://review.opendev.org/c/openstack/ironic/+/914772 which unpacks the cirros images before uploading them.
