MEDIUM: config: properly propagate process binding between proxies

We now recursively propagate the bind-process values between frontends
and backends instead of doing it during name resolving. This ensures
that we're able to properly propagate all the bind-process directives
even across "listen" instances, which are not perfectly covered at the
moment, depending on the declaration order.
