Provide a wrapped store type, exposing ExecTx method with a subset
interface in the callback argument. BaseDB interfaces in instantout,
reservation and sweepbatcher use ExecTx with their subset Querier
instead of whole sqlc.Querier (*sqlc.Queries).
This is needed to make the packages more reusable, so they don't
depend on methods of *sqlc.Queries they don't use.
A Querier holds the methods of sqlc.Querier interface relevant for a package.
BaseDB has Querier + ExecTx method.
This change is needed to simplify further rework of ExecTx.
This commit changes the way the reservation
manager works, by not exiting when the fetchL402
call fails. This ensures that a client can still
run loop, even if they don't have outbound
capacity or the loop server is offline.
This commit adds the reservation script file.
This file contains the neccessary function to create the
reservation script and addresses from the
pubkeys and expiry.
