Thanos sidecar has no limits set

[perk-sumo]

On of containers is not limited by default - and it should be as sumo warns about not-limited containers.

Container name: thanos-sidecar
StatefulSet name: prometheus-collection-prometheus-oper-prometheus
Helm chart version affected: all

There are no limits for thanos in the prometheus-operator values: https://github.com/helm/charts/blob/master/stable/prometheus-operator/values.yaml#L1961

User can set it as follows:
https://github.com/prometheus-operator/prometheus-operator/blob/master/Documentation/api.md#thanosspec

prometheus-operator:
  prometheus:
    prometheusSpec:
      thanos:
        resources: {}

Yeah, the thing is:

1. sumo k8s app warns about not-limited containers
2. thanos sidecar is not limited by default in the upstream chart like others

So you install the collection and instantly get the warning about collection, that's not a good experience.
