Instrumentation v1beta1 CRD with SDK schema

[pavolloffay]

Description:

Link to tracking Issue(s):

• Resolves: Updates Support OTel declarative configuration in the Instrumentation resource #4093

The SDK schema supports only: c++, java and go https://github.com/open-telemetry/opentelemetry-configuration/blob/main/language-support-status.md

The configuration schema is not supported for all languages supported by the operator (python, .net, nodejs, php...). Another problematic part is that the languages can support the schema only fractionally. This might pose problems with how these differences will be signaled to the operator users.

Testing:

kubectl get instrumentations.v1beta1.opentelemetry.io
kubectl get instrumentations.v1alpha1.opentelemetry.io
