lisa neigut de16d0f0b4 openchannel hook: add new close_to field
Rounds out the application of `upfront_shutdown_script`, allowing
an accepting node to specify a close_to address.

Prior to this, only the opening node could specify one.

Changelog-Added: Plugins: Allow the 'accepter' to specify an upfront_shutdown_script for a channel via a `close_to` field in the openchannel hook result

"""Simple plugin to test the openchannel_hook's
'close_to' address functionality.
If the funding amount is:
- a multiple of 11: we send back a valid address (regtest)
- a multiple of 7: we send back an empty address
- a multiple of 5: we send back an address for the wrong chain (mainnet)
- otherwise: we don't include the close_to
