IPMI configuration can be done directly with -e section:key

[Mark Shuttleworth]

We currently set IPMI configuration using a fragment of IPMI config (ipmi.conf in templates) which is sent to the BMC, along the lines of:

   ./ipmi-cmd -u X -p Y -h Z --commit -n <filename.cfg>

We can actually send the configuration much more directly, using the "-e section:key=value" pattern in freeipmi. So:

  ./ipmi-chassis-config -u ... -p ... -h ... --commit -e -e Chassis_Boot_Flags:Boot_Flags_Persistent=No

The -e section can be repeated several times on the command line, enabling us to set everything we need in a single transaction. The current IPMI config fragment would thus become:

 -e Chassis_Power_Conf:Power_Restore_Policy=Off_State_AC_Apply \
 -e Chassis_Boot_Flags:Boot_Flags_Persistent=No \
 -e Chassis_Boot_Flags:Boot_Device=PXE

The configuration subprocess exits with 0 on success, making for easy validation.

The way MAAS uses ipmi has changed since the issue was submitted.
