Payment methods from core source model are not grouped properly

[wojtekn]

Summary

There is \Magento\Payment\Model\Config\Source\Allmethods class in the Magento core which can be used as source model for backend configuration fields. It displays available payment methods grouped by payment provider. Not all methods shipped with M2 have group defined, so some of them are displayed outside option group. This can be confusing.

It looks as follows now:

Examples

1. Create empty custom module
2. Add new field to system configuration using mentioned source model:

    <group id="payment" translate="label" type="text" sortOrder="20" showInDefault="1" showInWebsite="1" showInStore="1">
        <label>Payment settings</label>
            <field id="ccmethods" translate="label" type="multiselect" sortOrder="1" showInDefault="1" showInWebsite="1" showInStore="1">
            <label>CC methods</label>
            <source_model>Magento\Payment\Model\Config\Source\Allmethods</source_model>
        </field>
    </group>

Proposed solution

Configure one missing group for PayPal method, one for Authorize.net method and a group for all Braintree methods.

I will submit PR for this soon.
