Add "ipmitool support"

ipmitool is a utility for controlling IPMI-enabled devices. It can be used to display information about the server, updating system firmware, rebooting/resetting the system, configuring network settings, read event logs, and a whole set of other things.

u-root has an IPMI library and an ipmidump command using it.

For a user who wants to f.ex. reconfigure the network settings, adding a BMC user or changing the password for an existing BMC user, it would be valuable to have this functionality in the provisioning stage. Assuming that the real service, implemented by the OS package to be run, will be stripped down and not have sshd and shell access and definitely not contain credentials to interact with the BMC, this would be the place to do it.
