wallet:

- add new index: requests_rhash_to_key (fixes #7845)
 - when creating a request, do not save its description in labels.
   Instead, return it as default value in wallet.get_label_by_rhash
lnworker:
  - rename 'payments' to 'payment_info'
  - add note to delete_payment_info
commands: rename 'rmrequest' to 'delete_request'
