NiFi default resources docs differ from actual defaults

[maltesander]

The docs for default resources and PVCs differ from what the operator sets as default
https://github.com/stackabletech/nifi-operator/blob/main/rust/crd/src/lib.rs#L321
vs
https://docs.stackable.tech/home/nightly/nifi/usage_guide/resource-configuration

Docs mention 2GB for all repos and less cpu.

Nightly and at least 23.11 affected.

Issue checklist

This is a simple checklist of things to bear in mind when creating a new issue.

• Describe the use-case, as far is possible. For instance, using the pattern "As a XXXX, I would like XXXX to be able to do XXXX" helps to identify the feature as well as the problem it is intended to address.
• Indicate an approximate level of importance and urgency.
• Indicate if there is a known work-around until such time as the issue has been implemented.

I think my preferred solution is to document the defaults in the CRD docs, and just point to the CRD reference for these default values. For example for the flowfileRepo PVC we could document the default on this property: https://github.com/stackabletech/nifi-operator/blob/main/rust/crd/src/lib.rs#L409

This would be an improvement because then it is already closer to the code. I think it would be even better if the definition of the default was even closer to the documentation of it.

To simply fix this now I want to update the docs. We can think about a longer term solution afterwards:

• 23.7: fix(docs): Changed defaults documentation (23.7) #547
• 23.11: fix(docs): Changed defaults documentation (23.11) #548
• nightly: fix(docs): Add defaults to the CRD docs #549
