nvmet: Introduce get/set_feature controller operations
The implementation of some features cannot always be done generically by
the target core code. Arbitraion and IRQ coalescing features are
examples of such features: their implementation must be provided (at
least partially) by the target controller driver.
Introduce the set_feature() and get_feature() controller fabrics
operations (in struct nvmet_fabrics_ops) to allow supporting such
features.
