Add deviceinfo service info to info command (danielpaulus#155)

I added two new fields to the info command. The response of hardwareInformation and networkInformation from the instruments service are now in the results if a developer image is mounted.
hardWareInformation contains various cpu infos. Here is an example:
map[hwCPU64BitCapable:1 hwCPUsubtype:1 hwCPUtype:16777228 numberOfCpus:2 numberOfPhysicalCpus:2 speedOfCpus:0]

networkInformation contains a list of all network interfaces on the device. Example:
map[en0:Wi-Fi en1:Ethernet Adaptor (en1) en2:Ethernet Adaptor (en2) lo0:Loopback pdp_ip0:Cellular (pdp_ip0)
pdp_ip1:Cellular (pdp_ip1) pdp_ip2:Cellular (pdp_ip2) pdp_ip3:Cellular (pdp_ip3) pdp_ip4:Cellular (pdp_ip4)]

Those are now part of the ios info command output only if the developer image was mounted on the device.
