bug: ChangeDetectionStrategy.OnPush Schematics

[Lindsor]

Bug Report

Angular CLI allows us to add Schematics for default ChangeDetectionStrategy
Ionic should allow for that as well. Default change detection strategy is a performance hit so i want to default to OnPush.
This setting should be looked at both when generating "Page" and "Component".

Ionic version:
[ ] 4.x
[x] 5.x

Steps to reproduce:

npx ionic g page test-page
npx ionic g c test-component
Check the generated code and see no ChangeDetectionStrategy.OnPush
