cloud: use uuid as bucket name

Previously, the GCS and S3 tests used hard coded bucket names to test
the behavior of buckets that do not exist. Now, the tests use a random
UUID. This change is necessary because someone appears to have created
the GCP bucket which causes the test to fail.

Release Justification: Test Only Change
