Previously, a user could inadvertently override the type or the inputs value by specifying those in their config. Instead, we force-set these so that users do not have potentially invalid config.
As per documentation, the `/var/log/dokku/apps` should be mounted from the host to the container. The existing mount was `/var/log/dokku` mounted to `/var/logs/dokku/apps`.
The broken mount will be removed in the next minor.
dburl adds aliases for everything, which breaks if two schemes are similar enough (anything with `aws_` as a prefix broke scheme registration). It does not appear to add anything, so we'll drop that dependency.
Also remove go-jsonmerge, as this was refactored to use structs instead of byte manipulation...
