What does this MR do and why?
svga/ci: re-enable vmware farm
Re-enable the farm after an outage. Latter was caused by lava-ci running out
of free space after accumulation of artifacts, mainly docker images. Mend by:
* setting a cronjob for docker system prune --all --volumes
* bumping up lava-ci fs to 128GB
