This could be useful if we want to create one-time use layers on the flight and not worry about memory leaks (one time used layers that are not removed constitute a memory leak in a sense).

I would like to re-introduce in the pay command (
xpay-handle-pay=true) the possibility of excluding channelsand nodes using the legacy pay style
excludeparameter.One possible solution is to create a one-time layer with all the channels and nodes listed in the
excludearray as disabled and then pass the call to
xpaywith that temporary layer in the parameters.We make this one-time layer possible by introducing expiration times to layers in this PR.
