SKIP UPGRADE Add testing with prometheus thanos-sidecar installed with monitoring

for big-bang/bigbang#1792 (closed)

Due to the design of thanos/prometheus interaction and the limitation of passing values to monitoring:prometheus, the Thanos testing with Prometheus will be enabled with the bigbang tests and not at the Thanos package level. The package level testing will make sure Thanos is up and run a simple query.

Note: The upgrade task is failing which is expected:

Error: rendered manifests contain a resource that already exists. Unable to continue with install: NetworkPolicy "allow-instance-egress" in namespace "minio-operator" exists and cannot be imported into the current release: invalid ownership metadata; annotation validation error: key "meta.helm.sh/release-name" must equal "miniooperator": current value is "istiooperator"

The key in dependencies.yaml was changed to minio-operator which is different from the previous version and causes the upgrade to fail
