[CORE-3388] Payflow: Update to use configuration file - Blesta

Details

Update the Payflow gateway to use a configuration file. All attributes should be set, and the methods in the gateway that the config file replaces should be removed.
- See https://docs.blesta.com/display/dev/Gateway+Configuration
Also set a translated description in the config.
This is a great time to add/update the README for the gateway
- Set a table description in the README of what versions of Blesta work for what versions of the gateway (e.g. like Vesta)
