This is a change to the `config.json` file which removes certain options
that are best not touched and changes some options to make them easier
to work with.
1. We change the default journaling mode to "wal" and remove the config
option.
2. We remove the option to set the peer connection "target", as it's not
a good idea to set this to a different value, as it affects the
network.
3. We combine seeding policy & scope, since there's no need to set the
scope when the policy is "block". In that case, we always want to
block "all" remotes. The new policy configuration has the following
schema:
{ seedingPolicy: { default: "block" | "allow", scope?: "all" | "followed" } }
The "scope" key is not used when "default" is set to "block".
4. We add an `extra` field to the node config for options that are not
recognized. We use this to warn the user.
This makes the default policy `block` with scope `all`. The good thing
about this is that you don't have to manage individual nodes in the
beginning. You simply seed the repos you want, and everything is
followed within those repos. This matches user expectations, as `rad
seed` does what you expect it to do.
For open-policy seed nodes, it also means that simply changing `block`
to `allow` from the default config is all you need.
This leaves the non-default `followed` scope as a more "advanced"
setting, since it is much more cumbersome: it forces you to follow a
user before you can see their issues/patches, which is not something
most users expect coming from old-shcool forges.
