/**
* Implemented by subclasses. The responsibility of this method is to contact the service provider
* at the given endpoint URL and fetch a request or access token. What kind of token is retrieved
* solely depends on the URL being used.
*
* <p>Correct implementations of this method must guarantee the following post-conditions:
*
* <ul>
* <li>the {@link OAuthConsumer} passed to this method must have a valid {@link
* OAuth#OAUTH_TOKEN} and {@link OAuth#OAUTH_TOKEN_SECRET} set by calling {@link
* OAuthConsumer#setTokenWithSecret(String, String)}
* <li>{@link #getResponseParameters()} must return the set of query parameters served by the
* service provider in the token response, with all OAuth specific parameters being removed
* </ul>
*
* @param consumer the {@link OAuthConsumer} that should be used to sign the request
* @param endpointUrl the URL at which the service provider serves the OAuth token that is to be
* fetched
* @param additionalParameters you can pass parameters here (typically OAuth parameters such as
* oauth_callback or oauth_verifier) which will go directly into the signer, i.e. you don't
* have to put them into the request first, just so the consumer pull them out again. Pass
* them sequentially in key/value order.
* @throws OAuthMessageSignerException if signing the token request fails
* @throws OAuthCommunicationException if a network communication error occurs
* @throws OAuthNotAuthorizedException if the server replies 401 - Unauthorized
* @throws OAuthExpectationFailedException if an expectation has failed, e.g. because the server
* didn't reply in the expected format
