qmp/hmp: add rocker device support

Add QMP/HMP support for rocker devices.  This is mostly for debugging purposes
to see inside the device's tables and port configurations.  Some examples:

(qemu) info rocker sw1
name: sw1
id: 0x0000013512005452
ports: 4

(qemu) info rocker-ports sw1
            ena/    speed/ auto
      port  link    duplex neg?
     sw1.1  up     10G  FD  No
     sw1.2  up     10G  FD  No
     sw1.3  !ena   10G  FD  No
     sw1.4  !ena   10G  FD  No

[Added "query-" prefixes to rocker.json commands as suggested by Eric
