Alexey Marchuk 3d8904c66b nvmf: Add discovery filtering rules
SPDK nvmf target reports all listeners on all subsystems
in discovery pages, kernel target reports only subsystems
listening on a port where discovery command is received.

NVMEoF specification allows to specify any addresses/
transport types. Ch 5: The set of Discovery Log entries should
include all applicable addresses on the same fabric as the
Discovery Service and may include addresses on other fabrics.

To align SPDK and kernel targets behaviour, add filtering
rules to allow flexible configuration of what should be
listed in discovery log page entries.

Fixes #2082
