/**
 * Task that will return the bind interface and ports being used by the admin
 * console of the node where the task will be executed. When the admin console
 * is binded to all network interfaces this task will try to find a valid IP
 * address that will work for the remote node.
 *
 * A null bindInterface in the result of this task means that the task
 * failed to find a valid IP address where the admin console is listening.
