closingd: configurable closing fee negotiation step When negotiating the transaction fee for closing a channel [1], we used to always pick the middle of the range between our proposal and the peer's proposal. Introduce a new option `fee_negotiation_step` to the close command, so the peer who initiates the close can choose his back off step. Partially resolves https://github.com/ElementsProject/lightning/issues/3270 [1] https://github.com/lightningnetwork/lightning-rfc/blob/master/02-peer-protocol.md#closing-negotiation-closing_signed Changelog-Added: New optional parameter to the `close` command to control the closing transaction fee negotiation back off step
