What happened?

Description

I tried to use a field supported by TA and bumped into an issue of these values not being synchronized, so I cannot use a fallbackStrategy to query a couple of targets that are not bound to a "node" object (i.e. kube apiserver serviceMonitor)
i.e. here are the settings for opentelemetry-kube-stack where I create a target-allocator daemonset to collect metrics from various services.
It gets passed as is to the operator

target-allocator:
    targetAllocator:
      allocationStrategy: per-node
      allocationFallbackStrategy: consistent-hashing

The flag, while it can be assumed to be valid, is not passed through the layers of helm -> operator -> collector

Steps to Reproduce

set allocationFallbackStrategy (or any TA config option from the config.go schema converting it snake_case -> camelCase)

Expected Result

a correspondingly configured Collector object is created

Actual Result

the field is dropped
