Attempts to extract information from HP iLO boards including versions and addresses.

HP iLO boards have an unauthenticated info disclosure at <ip>/xmldata?item=all.
It lists board informations such as server model, firmware version,
MAC addresses, IP addresses, etc. This script uses the slaxml library
to parse the iLO xml file and display the info.
