OpenWrt integration key value support

[Nick]

Good day,

Just putting it out there that there has been some progress on this.  It seems to be almost fully working.  Everything except for the secondary DNS server is able to be retrieved and used by the MM service.  It’s a shell script, perhaps someone with more experience would spot the problem quickly, either on line 363 or around line 104.  I am still working on it when I have time.

Best,

Nicholas
