/**
* Features that provides Http Basic and Digest client authentication (based on RFC 2617).
* <p>
* The feature can work in following modes:
* <ul>
* <li><b>BASIC:</b> Basic preemptive authentication. In preemptive mode the authentication information
* is send always with each HTTP request. This mode is more usual than the following non-preemptive mode
* (if you require BASIC authentication you will probably use this preemptive mode). This mode must
* be combined with usage of SSL/TLS as the password is send only BASE64 encoded.</li>
* <li><i>BASIC NON-PREEMPTIVE:</i> Basic non-preemptive authentication. In non-preemptive mode the
* authentication information is added only when server refuses the request with {@code 401} status code and
* then the request is repeated with authentication information. This mode has negative impact on the performance.
* The advantage is that it does not send credentials when they are not needed. This mode must
* be combined with usage of SSL/TLS as the password is send only BASE64 encoded.
* <p/>
* Please note that when you use non-preemptive authentication, Jersey client will make 2 requests to a resource,
* which also means that all registered filters will be invoked twice.
* </li>
* <li><b>DIGEST:</b> Http digest authentication. Does not require usage of SSL/TLS.</li>
* <li><b>UNIVERSAL:</b> Combination of basic and digest authentication. The feature works in non-preemptive
* mode which means that it sends requests without authentication information. If {@code 401} status
* code is returned, the request is repeated and an appropriate authentication is used based on the
* authentication requested in the response (defined in {@code WWW-Authenticate} HTTP header. The feature
* remembers which authentication requests were successful for given URI and next time tries to preemptively
* authenticate against this URI with latest successful authentication method.
* </li>
* </ul>
* </p>
* <p>
* To initialize the feature use static method of this feature.
* </p>
* <p>
* Example of building the feature in
* Basic authentication mode:
* <pre>
* HttpAuthenticationFeature feature = HttpAuthenticationFeature.basic("user", "superSecretPassword");
* </pre>
* </p>
* <p>
* Example of building the feature in basic non-preemptive mode:
* <pre>
* HttpAuthenticationFeature feature = HttpAuthenticationFeature.basicBuilder()
* .nonPreemptive().credentials("user", "superSecretPassword").build();
* </pre>
* </p>
* <p>
* Example of building the feature in universal mode:
* <pre>
* HttpAuthenticationFeature feature = HttpAuthenticationFeature.universal("user", "superSecretPassword");
* </pre>
* </p>
* <p>
* Example of building the feature in universal mode with different credentials for basic and digest:
* <pre>
* HttpAuthenticationFeature feature = HttpAuthenticationFeature.universalBuilder()
* .credentialsForBasic("user", "123456")
* .credentials("adminuser", "hello")
* .build();
* </pre>
* </p>
* Example of building the feature in basic preemptive mode with no default credentials. Credentials will have
* to be supplied with each request using request properties (see below):
* <pre>
* HttpAuthenticationFeature feature = HttpAuthenticationFeature.basicBuilder().build();
* </pre>
* </p>
* <p>
* Once the feature is built it needs to be registered into the {@link javax.ws.rs.client.Client},
* {@link javax.ws.rs.client.WebTarget} or other client configurable object. Example:
* <pre>
* final Client client = ClientBuilder.newClient();
* client.register(feature);
* </pre>
* </p>
*
* Then you invoke requests as usual and authentication will be handled by the feature.
* You can change the credentials for each request using properties
* {@link org.glassfish.jersey.client.authentication.HttpAuthenticationFeature#HTTP_AUTHENTICATION_USERNAME} and
* {@link org.glassfish.jersey.client.authentication.HttpAuthenticationFeature#HTTP_AUTHENTICATION_PASSWORD}. Example:
* <pre>
* final Response response = client.target("http://localhost:8080/rest/homer/contact").request()
* .property(HTTP_AUTHENTICATION_BASIC_USERNAME, "homer")
* .property(HTTP_AUTHENTICATION_BASIC_PASSWORD, "p1swd745").get();
* </pre>
* <p>
* This class also contains property key definitions for overriding only specific basic or digest credentials:
* <ul>
* <li>
* {@link org.glassfish.jersey.client.authentication.HttpAuthenticationFeature#HTTP_AUTHENTICATION_BASIC_USERNAME} and
* {@link org.glassfish.jersey.client.authentication.HttpAuthenticationFeature#HTTP_AUTHENTICATION_BASIC_PASSWORD}
* </li>
* <li>
* {@link org.glassfish.jersey.client.authentication.HttpAuthenticationFeature#HTTP_AUTHENTICATION_DIGEST_USERNAME} and
* {@link org.glassfish.jersey.client.authentication.HttpAuthenticationFeature#HTTP_AUTHENTICATION_DIGEST_PASSWORD}.
* </li>
* </ul>
* </p>
