Remove performSpecUpdate(boolean) from Set<Operation>Output. (#132)

Issue #, if available: aws-controllers-k8s/community#812

Description of changes:
* Do not restrict Create and Update operation output to only updating the Status of latest k8s resource. This change will allow both Spec and Status of latest object to be updated.
* Removing of conditional "performSpecUpdate" will allow both Spec and Status fields to be updated.
* This will allow server-side-defaults to be populated into the k8s latest object. Server-side-defaults are the default values added by AWS service upon resource creation/update when these optional values were not specified by the user.
