Create grpc connection only on invocation of the CRUD events for the installation controller

[troy0820]

Before this change we were creating a persistent connection with the grpc server when starting the controller manager. This led to problems decoupling that connection when starting the operator. Now this connection will only be established if the creation/update of an installation is done. This will reduce the overhead of that established connection as well as not being able to reestablish this connection on subsequent calls if not done at startup.

What does this change

• Creates the grpc connection when the controller is invoked on a CRUD event for the installation controller

What issue does it fix

No issue but discussed during the maintainers call

Notes for the reviewer

This doesn't impact anything as this image shows that this still works, just changes the implementation around how we establish a connection with the grpc server
