Context

Currently, when an Open Payments GET wallet address request is made, if the wallet address isn't found, we create a wallet address not found webhook event, such that the ASE can have a chance to "create the wallet address on the fly", if that is what their configuration requires.

Now, we would like to put that behind an environment variable, and make it disabled by default so we don't spam webhook events for integrators who don't want/need to support this.

Todo

• Add WALLET_ADDRESS_NOT_FOUND_POLLING_ENABLED backend environment flag, false by default
