* Add support for service fees
This introduces a new transaction type "service_fee"
Each outgoing payment is charged a service fee of x/1000.
The service fee entries is added with the routing fee reserve entry.
For failed payments the service fee is reversed.
* Add service_fee migration
* No service fee by default
* Fee reserve and service fee is optional
ignore NoRows errors
* Update Makefile
* Unify setting the fee on the invoice
* Proper error check
* ups
* Add service fee tests to outgoing payment tests
* Save parant id to fee tx entries
* Optionally load test DB from env variable
* Add config for free transactions
payment amounts up to NO_SERVICE_FEE_UP_TO_AMOUNT don't get a service fee charged
* Update readme
* cleanup
* fix: only charge service fees for amounts > free limit
* fix: format
* Save service fee on invoice
* naming
* Also save the payment hash where we save the preimage
we already do exactly that when in the normal PayInvoice flow.
Normally the RHash is already set here, but I guess it does not hurt to have
it consistent everywhere.
* Use the invoice routing fee field to check if a routing fee must be charged
It feels a bit indirect to check if we have set a FeeReserve.
We save the routing fee on the invoice thus we should be able to use that information
* remove nullzero from fee columns
we want those to be 0 by default
* add columns only if not existent

* Update Makefile
* Optionally load test DB from env variable
* Add option to soft-delete a user
This allows users to be marked as deleted.
An additional middleware checks if a user is deleted or deactivated and rejects
requests for those as StatusUnauthorized.
note: the middelware adds an additional DB query to load the user.
