/**
 * {@link RememberMeServices} proxy.
 *
 *  In Hudson, we need {@link Hudson} instance to perform remember-me
 * service, because it relies on {@link Hudson#getSecretKey()}. However,
 * security filters can be initialized before Hudson is initialized. (See #1210
 * for example.)
 *
 *  So to work around the problem, we use a proxy.
