Username workaround

[SnAp227]

I don't know if anyone has noticed, but the default user name for edge devices has always been admin. Part of my default config was to change this to another more discrete name. This worked great in 5.x code however in the new 6.x code (and probably the 7.x) they removed the ability to change the user name from admin. The work around I found is to export the config, then modify the exported config file and look for the user name "admin" within the file. Replace it with whatever you would like it to be, then re-import the file. This hasn't caused any problems at all with any of my edge devices. Hopefully this helps someone because it irritated me that they did it.
