[bitnami/thanos] Query multiple object storage buckets from Thanos instance

[MysterioO]

Our current set-up is that we have to have multiple metric buckets to separate certain cluster data. We are wanting to switch to Thanos bitnami helm chart. Currently we are having individual thanos-store pods for each bucket, however on first glance this is not possible with Thanos helm chart. We are considering maybe deploying a sidecar for each object storage in storegateway statefulSet, but interested if others are using different/better approach.
