Story (Required)

As an OpenShift user, I would like to have ClusterWorkloadResourceMapping resources validated for me on submission.

Background (Required)

With the introduction of APPSVC-970, we now have to manage ClusterWorkloadResourceMapping resources.  We should validate them on submission, rather than throw an error when we try to resolve a service binding that uses a mapping.

In Scope

Adding a validation webhook to SBO.

Approach(Required)

Write a validation webhook that accepts these resources.  The webhook.Validator interface from OperatorSDK is going to be the easiest method for validation.

Dependencies

https://github.com/redhat-developer/service-binding-operator/pull/1086 needs to land first.

Acceptance Criteria

• Given SBO is running, when I submit an invalid workload resource mapping, then I should receive a validation error.
• Validation errors should point out specific errors.  Ex: If I submit an invalid json path, then the validation error should point out which field is invalid.
• Make sure unit test are implemented
• Acceptance Test Scenarios added
