Not sure if NetworkManager uses dhclient underneath, but if it does then 
you can probably use dhclient.conf(5), which lets you override, add 
local settings etc.

Alternatively, from the NetworkManager man page:

        "NetworkManager will execute scripts in the 
/etc/NetworkManager/dispatcher.d
               directory in alphabetical order in response to network 
events."

It should be fairly trivial to add a script here which is executed 
automatically when NetworkManager brings an interface online to 
append/insert additional lines into /etc/resolv.conf
