Changelog-Fixed: doc: Epic documentation rewrite: each now lists complete and accurate JSON output, tested against testsuite.
Allows us to clean up an in-progress open that we won't be completing
Changelog-Added: EXPERIMENTAL JSON-RPC: Permit user-initiated aborting of in-progress opens. Only valid for not-yet-committed opens and RBF-attempts
`openchannel_signed` and `openchannel_update` which allow a user to
continue a openchannel or kick off the completion of a openchannel.
`openchannel_update` should be called until it returns with
`commitments_secured`.
