Reflect changes in Testgrid config post s3 migration and prow.tanzu.io migration

[rajaskakodkar]

This is a follow-up on migration of prow logs to S3.

Front end of testgrid could be generated with the changes in this PR.

However, testgrid backend has updater controller which checks for Prow job logs and populates cells in testgrid. This controller currently accepts only GCS buckets for source of truth of Prow job logs and does not work with S3.

{"config":"gs://vagator-testgrid/config","error":"read first column: group path: gs://bucket may not contain a port: gs://s3:/tanzu-prow-logs/logs/post-test-image/","file":"pkg/updater/updater.go:378","func":"github.com/GoogleCloudPlatform/testgrid/pkg/updater.Update.func
2","group":"post-test-image","level":"error","msg":"Failed to update group","time":"2022-03-31T09:17:04Z"}

This PR should be merged only when updater supports S3.
