[bacherfl]

Goal

The goal of this issue is to move the CRDs from v1alpha3/v1alpha4 the new API version v1beta1.

Details

The v1beta1 version should have the following, which should have the same definition as in v1alpha3/v1alpha4, those are:

• KeptnApp
• KeptnAppCreationRequest
• KeptnAppVersion
• KeptnEvaluation
• KeptnTask
• KeptnTaskDefinition
• KeptnWorkload
• KeptnWorkloadVersion

The following v1alpha3 CRDs do not need to be moved to v1beta:

• KeptnEvaluationProvider
• KeptnWorkloadInstance

Acceptance Criteria

• new version v1beta1 contains the mentioned CRDs
• the new CRDs can be applied to the cluster where the lifecycle-operator is installed
• CRDs are part of helm charts
• CRD documentation is re-generated

DoD

should I create the create common for v1beta1 too ??

Sorry, @prakrit55 , but this is pretty important since many other tickets depend on this. That's why one of the core maintainers will implement it. Please feel free to take a different ticket :)

Hey @mowies, I think with a little acquaintance, I could settle it. I have seen the v1beta1 introduced in metrics-operator, so I already started it. If it still needs the maintainers then its okay from meee 🙂

Ok if you feel like you're up for it, then go ahead! 😄
If needed, somebody else can take over from you anyways :)
The metrics API change is definitely the best bet to see how it's all done 👍🏼
