Refactor earlier mutator implementations to use wildcard methodology - Istio Operator

Package Merge Request

Package Changes

Omits the serviceAccounts list in Istio Operator automountServiceAccountToken hardening, allowing the mutator to target all SAs via wildcard. This is more robust and better accommodates upstream changes over time.

At the moment, however, this is a simple refactor and there is no change to the original hardening.
