Various Refactoring to Istio Profiles Controller

[Collinbrown95]

Description

Various components of the Istio Profiles Controller will need to be refactored in light of the changes/recommendations to the standalone example.

TODO

• [ ] Each VirtualService needs an exportTo block to export to both the employee namespace and the cloud-main-system namespace.
• [ ] Need to refactor the current VirtualService that gets created by the controller to match the standalone example.
• [ ] Need to refactor the istio profile controller to add a per-namespace ServiceEntry with an exportTo block that exports to both employee namespace and cloud-main-system namespace.
• [ ] Need to refactor the istio profile controller to add a per-namespace DestinationRule with an exportTo block that exports to both employee namespace and cloud-main-system namespace.
