Well the default minimal install that I do (or use, done,did,etc) has

networkmanager, isc-dhcp-client and wpa_supplicant, so that is the 
parameters that I have to work under.  I would like not to change that 
by removing or adding packages if I can.

As I understand this networkmanager has an internal dhcp client.

It can setup all the other parameters.

Which is ok and will for me if I can get it to leave /etc/resolv.conf alone.

This is what I am trying to accomplish.

Barring that I am gonna try to get it to put the following into 
resolv.conf if it just has to write  that file

and call it a day,week or month whatever it takes

domain example.org
nameserver 127.0.0.1
options edns0 trust-ad
