Cleanup resolved object before validating through dry-run

[vdemeester]

Changes

This ensure that we are not going to fail during validation with dry-run. An example of such a failure would be the following scenario.

• A task in a namespace has ownerReferences with blockOwnerDeletion: true
• A user uses the cluster resolver to fetch that task
• That user doesn't have a lot of rights in that namespace (only listing Tasks for example).

cc @JeromeJu @chitrangpatel This probably need some tests (unit at least), a release note and some refactoring, but does the approach sounds alright ? Also, we can list other fields we may want to clean.

Right now, we only use dryRun to Validate. If users have mutating admission webhooks on the cluster then when we do the dryRun and validate, the mutations will happen before the validation. However, we ignore the mutated object and only continue with the original runtime Object even though we have validated the mutated one. In practice, when we do the dryrun, we should return the mutated object in addition to the validation error so that we use the mutated object in the underlying spec.

Ah that's a good point, we should probably track this into an issue.
