We now keep the VPN enable state, bandwidth limit enable and actual limits
in the core config to avoid having to recover "user intent" from different
config files when the used VPN packages change.
Fixes#1736
(cherry picked from commit 818c31afdd)
None of our scripts can handle fastd and tunneldigger running at the same
time. When both are installed, ignore tunneldigger.
(cherry picked from commit f6df3b0541)
The generic upgrade script is moved to run after the more specific scripts.
In addition, the script will now remove the configuration sections of
uninstalled VPN packages, so both positive and negative changes of the
default enable state can be migrated correctly.
