Updated the project go version to 1.22 to ensure envtest-setup setup-envtest@latest works (hard blocker). Please check this was recently moved to go 1.22 https://github.com/kubernetes-sigs/controller-runtime/commit/4c2442e4d743d172a2e0126a841ecd274fffc228#diff-d9a956120ac84289d2650137f64bd8f0893331de05e44cc41899dd984c9e0d48

@prudhvigodithi Didn't have time to look at the whole PR, but this one jumped out: Removing a field from the CRD is a breaking change and would require a major release. It would be easier to keep the field in the CRD for compatibility and just ignore it when communicating with the Opensearch API.

I agree with @swoehrl-mw - Otherwise it looks good although we should upgrade to 1.22.1 like @sunsrin suggested

[prudhvigodithi]

@prudhvigodithi do you want to use 1.22.1 - which is the latest stable release with few more security fixes - https://tip.golang.org/doc/devel/release#go1.22.minor or do you want to stick to major versions only ? thank you for looking into this - fell off my radar

Hey @sunsrin let me check with 1.22.1.

[prudhvigodithi]

Sure @swoehrl-mw @salyh let me check to ignore the field still keeping the CRD, I will try to add a logging when used allow_auto_create saying its not supported in OpenSearch, this way user will know that till is not applied for _component_templates. @bbarani

I have updated the code to retain the AllowAutoCreate, but when applied shows the following warning to the user, the allow_auto_create will not be adding to the _component_template

{"level":"debug","ts":"2024-03-28T13:03:49.105-0700","logger":"events","msg":"OpenSearch Component Index template does not support allow_auto_create","type":"Warning","object":{"kind":"OpensearchComponentTemplate","namespace":"default","name":"default-component-template","uid":"1286a7b0-39d2-400e-b165-ce7f6916a466","apiVersion":"opensearch.opster.io/v1","resourceVersion":"22502365"},"reason":"OpensearchAPIUpdated"}

Hey @sunsrin I have updated to 1.22.1, looks good.
