Wrap send_pay in awaitable channel futures #522
Description
It would be great if send_pay could be wrapped in awaitable channel futures, just like pay and trampoline_pay. The Breez SDK uses send_pay to pay for reverse swaps. They sometimes fail with failed: WIRE_TEMPORARY_CHANNEL_FAILURE (First peer not ready), meaning the channels between greenlight and the LSP are not yet reestablished at the moment of calling send_pay.

We have this patch pending deployment, but are fighting with the CI to get them deployed. I'll update here once the patches are deployed.

Follow-up pointer: the awaiting behavior implemented here later became a failure mode of its own — payments would block awaiting all channels, including abandoned/unfunded JIT opens that can never reappear. That was fixed by #759 (merged as
1d721b7c), which introduced a single channel-availability rule: unavailable channels are skipped for sends and invoices, and awaited channels fail fast when they will not come back.
