Payment methods and customer fields in checkout (simplified and hosted flow)
When forms are rendered in the checkout, we use getSpecificTypeFields in FormFields.php do decide which form fields that is required for a customer when a payment is initialized. In an early state, this method returned its full ruleset as an array when the method type was unknown, but since we also have to consider payment methods from Resurs Bank that we still not know of, we will return data fields from a new key in this method called "undefined". When there are methods of type unknown we will always return a default array of values instead of the full block of methods as this caused problems when PSP was enabled.

The admin functions are going into a more native state than before. Instead of bulked configuration rows, all settings are stored in wp_options per keyed row. See image below. This makes the configuration sections in the plugin less sensitive when it comes to serialized arrays. Everything are saved with a unique prefix that indicates that the data belongs to the plugin. The admininstration configuration are now also built with the WC_Admin_Settings API (output_fields method): https://docs.woocommerce.com/wc-apidocs/source-class-WC_Admin_Settings.html#191-671, which increases WooCommerce-version 3.4.0 as the least requirement.
