I'd love feedback from @rustyrussell and @CGuida on this since it is an alternative to #7288 |

Fixed 'default: null' which cln doesn't like on flag values (if you specify a default, it must be false). |
We didn't actually *change* the value you'd see, when we got a setconfig call! Changelog-Added: pyln-client: implement setconfig hook for plugins so you can see changes in `dynamic` options. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
I was looking into using the `threading.Condition` but since we're already rather heavily using callbacks, this allows us to stay single-threaded, and not having to completely hook the `setconfig` function. Changelog-Added: pyln-client: Added a notification mechanism for config changes
And don't set the value unless it passes. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
[ Fix not to include 'value' and 'default' (if None) in getmanifest response --RR ]

This is an alternative to #7288, that uses a callback per config
option rather than hooking the
setconfigfunction entirely. Thisallows us to react to individual config options changing, while still
maintaining the default
setconfigbehavior.
