In order to facilitate work to fix PUP-9041 we need the ability to detect if an LPAR is running as a NIM master or a NIM client.
This is open as a facter ticket right now, as I assume that's where we would add NIM master detection. Move the ticket to whatever project is appropriate if we need to do it elsewhere.
Added an new AIX specific fact that returns the type of the NIM configuration on. This will output 'master', 'standalone' or nothing if '/etc/niminfo' is missing.
