Make Payment methods enabled a global setting

[aschrammel]

Description
The configuration setting Payment methods enabled is shown across all scopes. No matter what scope is selected, the underlying backend model Adyen\Payment\Model\Config\Backend\PaymentMethodsStatus is always updating the default scope for the single payment methods.
This leads to inconsistencies between payment/adyen_abstract/payment_methods_active and all the single payment method configurations.

• Set Payment methods enabled to Yes in Default scope
• Having a Website A and a Website B in place
• Set Payment methods enabledto Yes in Website A scope

Expected Result
Payment methods are still active in Website B
Actual Result
Payment methods are deactived in Website B as well

Showing the configuration setting only in Default scope won't lead to such inconsistencies.

Tested scenarios
Stores > Configuration > Sales > Adyen > Accepting Payments > Payment methods > Payment methods enabled is a global setting

Hi @aschrammel,

Thank you for your efforts and contribution to improving our plugin. We appreciate the time and thought you put into your PR regarding making the configuration global.

After careful consideration, we've decided to proceed with a different approach that implements scopable configurations for payment methods. You can take a look at the PR we're moving forward with here.

We value your contributions and encourage you to continue sharing your ideas and improvements with us.

Kind regards,
Rok
