Rusty Russell f52ff07558 lightningd: allow delpay to delete a specific payment.

This is actually what the autoclean plugin wants, especially since
you can't otherwise delete a payment which has failed then succeeded.

But insist on neither or both being specified, at least for now.

Changelog-Added: JSON-RPC: `delpay` takes optional `groupid` and `partid` parameters to specify exactly what payment to delete.

lightning-delpay -- Command for removing a completed or failed payment

SYNOPSIS

delpay payment_hash status [partid groupid]

DESCRIPTION

The delpay RPC command deletes a payment with the given payment_hash if its status is either complete or failed. Deleting a pending payment is an error. If partid and groupid are not specified, all payment parts are deleted.

payment_hash: The unique identifier of a payment.
status: Expected status of the payment.
partid: Specific partid to delete (must be paired with groupid)
groupid: Specific groupid to delete (must be paired with partid)

Only deletes if the payment status matches.

EXAMPLE JSON REQUEST

{
  "id": 82,
  "method": "delpay",
  "params": {
    "payment_hash": "4fa2f1b001067ec06d7f95b8695b8acd9ef04c1b4d1110e3b94e1fa0687bb1e0",
    "status": "complete"
  }
}

RETURN VALUE

The returned format is the same as lightning-listsendpays(7). If the payment is a multi-part payment (MPP) the command return a list of payments will be returned -- one payment object for each partid.

On success, an object containing payments is returned. It is an array of objects, where each object contains:

id (u64): unique ID for this payment attempt
payment_hash (hex): the hash of the payment_preimage which will prove payment (always 64 characters)
status (string): status of the payment (one of "pending", "failed", "complete")
amount_sent_msat (msat): the amount we actually sent, including fees
created_at (u64): the UNIX timestamp showing when this payment was initiated
partid (u64, optional): unique ID within this (multi-part) payment
destination (pubkey, optional): the final destination of the payment if known
amount_msat (msat, optional): the amount the destination received, if known
completed_at (u64, optional): the UNIX timestamp showing when this payment was completed
groupid (u64, optional): Grouping key to disambiguate multiple attempts to pay an invoice or the same payment_hash
payment_preimage (hex, optional): proof of payment (always 64 characters)
label (string, optional): the label, if given to sendpay
bolt11 (string, optional): the bolt11 string (if pay supplied one)
bolt12 (string, optional): the bolt12 string (if supplied for pay: experimental-offers only).
erroronion (hex, optional): the error onion returned on failure, if any.

On failure, an error is returned. If the lightning process fails before responding, the caller should use lightning-listsentpays(7) or lightning-listpays(7) to query whether this payment was deleted or not.

The following error codes may occur:

-32602: Parameter missed or malformed;
211: Payment status mismatch. Check the correct status via paystatus;
208: Payment with payment_hash not found.
