Reconnecting with PIA makes Custom DNS go away.

[gholmann16]

Describe the bug
When I reconnect with PIA vpn, my custom DNS goes away, and in its place is a classic local DNS request.

To Reproduce
Steps to reproduce the behavior:

1. Go to Settings -> Network -> DNS -> Custom -> Primary 1.1.1.1 -> Secondary 8.8.8.8
2. /etc/resolv.conf is updated correctly

        nameserver 1.1.1.1
        nameserver 8.8.8.8

3. Disconnect and reconnect
4. /etc/resolv.conf is now set to a bad setting, which does not allow connection to the internet.

         # Generated by dhcpnameserver 8.8.8.8

         # /etc/resolv.conf.head can replace this line
        nameserver 10.0.2.1
        # /etc/resolv.conf.tail can replace this line

Expected behavior
It should maintain the resolv.conf

Observed on:
OS: Linux
Version: Arch Linux, Cinnamon DE

Is this still happening? Cannot reproduce in general. Perhaps a race condition where your dhcp is rewriting /etc/resolv.conf after the VPN connects?

It definitely was getting rewritten. I switched to using the "Use existing DNS option" and I just manually edit my resolv.conf, but obviously this is not a great solution.
