Draft: Increase Gitaly disk size on review apps for more IOPS
What does this MR do?
Give Gitaly larger disks to achieve adequate performance and avoid errors.
See #334342 (comment 614873815)
This might not be necessary if the Gitaly-related failures are resolved by the combination of the switch to SSDs and deploying Gitaly on non-preemptible VMs.
