That looks like what I want. I'll need to see if it is per interface
(which would be better) or per connection.
It turns out that solution is per connection/AP, not per interface. It also
doesn't let me do some things.
However, I found ifIput the config I want in /etc/dhcp/dhclient-wlan0.conf,
the config does get used by MetworkManager for any connection on that
wireless device. I can point to a local dns caching resolver and set
a domian search path that is useful for me.
This wasn't documented any place that looked official that I could find, but
Iran across the file name in a post while searching and gave it a try.
