The feature enables support for OAuth 1.0a on the server.
The OAuth 1 server support requires implementation of {@link OAuth1Provider}; which will be used to retrieve Request Tokens, Access tokens, etc. The implementation should be configured in this feature or registered as a standard provider.
Feature can be created and configured by various constructors. Beside that, the feature behaviour can be overwritten by configuration properties {@link OAuth1ServerProperties#ENABLE_TOKEN_RESOURCES}, {@link OAuth1ServerProperties#REQUEST_TOKEN_URI} and {@link OAuth1ServerProperties#ACCESS_TOKEN_URI}.
