Bulk add/modfiy ipmi-interfaces for existing devices

We had to add about 150 devices at once, each with IPMI. For adding we used of course the add_device.php script (very useful!). 

But in current version of observium we would have to go to each config of a device to assign an IPMI interface - of course not usable. 

So I wrote a script "add_ipmi.php" which is located in root-folder of observium. With this we could assign IPMI interfaces in bulk. 

for hi in {1..128}
do
{{  ./add_ipmi.php -h m${hi}.compute }}
{{      --ipmi-level administrator }}
{{      --ipmi-host m${hi}-ipmi.service }}
{{      --ipmi-interface lanplus }}
{{      --ipmi-user ADMIN }}
      --ipmi-pass XXXX
done

I think this could be very helpful - if you like you can take this, too.
