'man NetworkManager' is a good place to start here, which leads you to
NetworkManager.conf, which leads you to:

dns=dnsmasq

which with 0.9.6 and any options you put into custom configuration
in /etc/NetworkManager/dnsmasq.d, should do exactly what you want.  The
local caching nameserver functionality has actually been around for
quite a few years.  Also, on per-connection basis, NM allows appending
custom search domains to the list returned by the DHCP server, or as
you've found you can hijack the dhclient config files to do what you
want too.

As always, more documentation would be awesome; we've got a wiki but we
can also add stuff to a FAQ in git too.
