Allow CRDs custom apply order

[mattia-fumo]

Is your feature request related to a problem? Please describe.
At the moment the order in which resources are applied is hardcoded. This limits the usage of custom resources because it does not allow to customize the order for these resources (unknown resource types are by default applied at last).

Describe the solution you'd like
It would be very useful to override the default application order. For example this could be done using a new parameter (i propose --override-resources-order) that takes the name of the resources' kind in the wanted order.
