pbrd: implement `set *` and `match *` config replacement

Implement the ability to replace any existing `set *` or
`match` with another one or adding more config without having
to first delete the original config already there.

Before, we needed to constantly execute a `no` command for everything
to remove the rule before making changes to it. With this
patch, you can replace configs on individual sequences much
easier.
