Pulling COSA from quay takes a good amount of time. Let's bump this so the service doesn't timeout like has been seen: ``` Jan 27 13:27:10 localhost systemd[1]: Starting Boot VM over iSCSI... Jan 27 13:28:21 localhost chronyd[1116]: Can't synchronise: no selectable sources Jan 27 13:28:21 localhost chronyd[1116]: Source 149.28.200.179 replaced with 67.217.246.204 (2.rhel.pool.ntp.org) Jan 27 13:31:16 localhost systemd[1289]: Created slice User Background Tasks Slice. Jan 27 13:31:16 localhost systemd[1289]: Starting Cleanup of User's Temporary Files and Directories... Jan 27 13:31:16 localhost systemd[1289]: Finished Cleanup of User's Temporary Files and Directories. Jan 27 13:31:26 localhost systemd[1]: coreos-iscsi-vm.service: start operation timed out. Terminating. Jan 27 13:31:26 localhost systemd[1]: coreos-iscsi-vm.service: Main process exited, code=exited, status=1/FAILURE Jan 27 13:31:26 localhost systemd[1]: coreos-iscsi-vm.service: Failed with result 'timeout'. ``` (cherry picked from commit c4a64ab)
We've seen errors in the RHCOS pipeline where the iSCSI tests are hitting the 10m timeout. We could bump the timeout, but first let's try pulling the COSA image in a separate unit so that it can happen in parallel with the install over iSCSI so that when we're ready to start the VM the image is already there. (cherry picked from commit d3ec501)
In this case we'll run the podman container with --rootfs instead of pulling a full 4+ GiB COSA image from quay for `kola qemuexec`. This saves us quite a bit of time and bandwidth usage during a pipeline run because we have more than 1 iscsi test. This should also take care of coreos/fedora-coreos-tracker#1866 because we are no longer pulling this particular container from quay. (cherry picked from commit 8dbfe3e)

All of these patches should be in the latest OSBuild RPMs in Fedora 40 so we should be good to drop these.
