1. Proposed title of this feature request

Configurable Resources for all Prometheus Containers

2. What is the nature and description of the request?

When configuring requests and limits as mentioned in :

https://access.redhat.com/solutions/3867881

they only affect the prometheus container of the prometheus-k8s pods, but all other containers in the pod can not be configured this way.

3. Why does the customer need this? (List the business requirements here)

When executing resource intensive prometheus queries the thanos-sidecar container can consume a large amount of memory which can result in memory pressure on the nodes where the prometheus-k8s pods run on. This can force the node to become unresponsive which affects all pods running on the affected node (for example the router pods) which can make the cluster inaccessible until the nodes recover.

4. List any affected packages or components.
