The fetchinvoice RPC command contacts the issuer of an offer to get
an actual invoice that can be paid. It highlights any changes between the
offer and the returned invoice.
If fetchinvoice-noconnect is not specified in the configuation, it
will connect to the destination in the (currently common!) case where it
cannot find a route which supports option_onion_messages.
The offer must not contain send_invoice; see lightning-sendinvoice(7).
msatoshi is required if the offer does not specify
an amount at all, otherwise it is not allowed.
quantity is is required if the offer specifies
quantity_min or quantity_max, otherwise it is not allowed.
recurrence_counter is required if the offer
specifies recurrence, otherwise it is not allowed.
recurrence_counter should first be set to 0, and incremented for
each successive invoice in a given series.
recurrence_start is required if the offer
specifies recurrence_base with start_any_period set, otherwise it
is not allowed. It indicates what period number to start at.
recurrence_label is required if recurrence_counter is set, and
otherwise is not allowed. It must be the same as prior fetchinvoice
calls for the same recurrence, as it is used to link them together.
timeout is an optional timeout; if we don't get a reply before this
we fail (default, 60 seconds).
payer_note is an optional payer note to include in the fetched invoice.
