staging: cache_bucket = "org-wikimedia-releng-cloud-runner-staging-cache2"
Change the name of the cache_bucket to work around a prior mistake. When you try to delete a Space in the DigitalOcean UI, it says:
"Deleting a Spaces Bucket can take several days depending on the amount of data. During this time, the name of the Spaces Bucket cannot be reused and you will NOT be billed for the Spaces Bucket."
