Proxy Sidecar Resource Consumption

[LZ58840]

Hello, I primarily work with a large cluster (running a couple hundred Pods) where most of our deployments regularly interact with Azure resources via Azure Managed Identity. The proxy sidecar is needed because all our deployments use the Azure Go SDK which still hasn't been officially updated to use the Workload Identity Controller. With the upcoming deprecation of Pod Identity (which we are currently using) and the wait for the unreleased SDK update to consider, I would like to know:

1. How much CPU and memory a proxy sidecar container consumes per Pod.
2. If it is possible to place resource requests and limits on a proxy sidecar container. We are currently trying to determine and enforce reservations for every deployment we have in order to ease pressure on our quotas, thus wary of having many of these sidecars running on many Pods.

Kindly thanks!
