AUTHENTICATION_METHOD is deprecated as of allauth v65.4

[browniebroke]

Django-allauth deprecated their AUTHENTICATION_METHOD in version 65.4 and replaced it with a new setting:

To make way for a future "phone" method, AUTHENTICATION_METHOD was removed in favor of a new LOGIN_METHODS.

I noticed that I still had some warnings being logged while running tests in my project and it seems that they come from usages in dj-rest-auth

I started to look at how to handle this and was wondering what option to take:

1. support both AUTHENTICATION_METHOD and LOGIN_METHODS settings, leaving the minimum required allauth version as is
2. support LOGIN_METHODS only (drop support for AUTHENTICATION_METHOD) and bump the minimum version of allauth to >= 65.4

Any progress on this? I think Option 1 would be best.

-- Update the base dj-rest-auth backage to use LOGIN_METHODS by default.
-- Support user provided overrides to AUTHENTICATION_METHOD but inform about the all_auth warnings.
-- User provided LOGIN_METHODS fully supported without warnings.

I've opened a pull request with option 1: #681
