Controller should support certificateRefs #886
Description
Is your feature request related to a problem? Please describe.
It is not ideal to have to use the certificate ARN when creating a Gateway resource with HTTPS listeners. Using certificateRefs is far easier to make modular, especially when using the ACK controllers. Both the Gateway and the ACM resource can be in the same module, with one referencing the other.
Describe the solution you'd like
The Controller should support using certificateRefs
