/**
 * An extension of AdminRequest for messages that are used as part of the new CLI. The new CLI
 * expects errors to be logged on the side where the message is processed, which none of the rest of
 * gemfire messages do. This is a extension of AdminRequest so that old admin messages which are
 * still used as part of the new CLI still log the message.
