Enable CPU/Memory Requests/Limits for Istio Proxy on Fluentbit DaemonSets

During upgrades it appears that Fluentbit pods have issues coming online. Further investigation revealed the istio proxy was running out of memory and causing the pods to cycle over and over. The issue eventually clears itself, but it can take up to an hour for it finally clear.

Currently those istio settings can only be done globally which would result in all proxies increasing their memory even though we only see the problem in that specific component. Ideally, we'd like to be able to apply the CPU and Memory Requests and Limits only to the Fluentbit package itself.
