Add deletion policy annotation on all installations

[troy0820]

What does this change

This will add the annotation that we will use to determine how we want to delete the resources (installations and otherwise) to adopt the pattern from cross-plane as noted in issue #297

This is still in draft

All this does is just add the annotation, the WIP will use this to implement the logic behind this new annotation.

What issue does it fix

Partially closes #297
