nvmet: introduce new max queue size configuration entry

Browse source

Using this port configuration, one will be able to set the maximal queue
size to be used for any controller that will be associated to the
configured port.

The default value stayed 1024 but each transport will be able to set the
its own values before enabling the port.

Introduce lower limit of 16 for minimal queue depth (same as we use in
the host fabrics drivers).
