Fix can not resolve www.a.com, while a.com is `search a.com` in /run/NetworkManager/resolv.conf and /run/systemd/resolve/resolv.conf, I think `search a.com` is from router.
Fix after suspend can not connect to internet due to mullvad and networkmanager fighting over /etc/resolv.conf and cause resolv.conf be empty. (not sure the cause is correct). This can also be fixed by symlink using systemd-resolved see below.
I do not know why this fix work. I find this fix through trail and error. These changes in configs uses mullvad-vpn, openresolv, dnsmasq, avahi-daemon, and networkmanager. The features are dns cache (dnsmasq) and mdns (avahi-daemon).
The best way to use systemd-resolved with dns cache is `sudo ln -rsf /run/systemd/resolve/stub-resolv.conf /etc/resolv.conf`. But I can not find a way to fix the issue of not resolve www.a.com see above. I **guess** the most likely way for systemd-resolved to work is somehow config systemd-resolved to not get DNS from router.
