## Motivation
We have the machines redcurrant running with pvm_hmc and grenache running with spvm. Both are more or less doing the same but being separate ressources in OSD makes both always scarce. We should switch grenache to pvm_hmc as well.
## Acceptance criteria
* **AC1:** Both redcurrant+grenache run pvm_hmc OSD production jobs
* **AC2:** No more jobs are scheduled with spvm on OSD
* **AC3:** No OSD workers remain with spvm
## Suggestions
* Wait for at least both redcurrant+grenache available, i.e. wait for #139112 and #139199
* Inform users and ask them to schedule only pvm_hmc jobs
* Remove the machine definition in OSD
* Switch off all grenache spvm instances
* Do `chcomgmt -o setmaster -t norm -m grenache`
* Adapt settings like https://gitlab.suse.de/openqa/salt-pillars-openqa/-/blob/master/openqa/workerconf.sls#L1176-1180 but for grenache
* Ensure that both redcurrant+grenache happily work on pvm_hmc OSD production jobs
