Inconsistent object declaration

[maruina]

We are not consistent when we declare a new object.

Sometimes we do something like

pr := deploymentskyscannernetv1alpha1.ProgressiveRollout{}

and sometimes we do

pr := &deploymentskyscannernetv1alpha1.ProgressiveRollout{}

We agreed on using the first format because then it's very explicit when you need to pass a reference to it. For example

if err := r.Get(ctx, req.NamespacedName, &pr); err != nil {...}

is more clear then

if err := r.Get(ctx, req.NamespacedName, pr); err != nil {...}
