/** Provides universal API for transport connections.
 *
 * Transport connection is a low-level object that wraps a connection method
 * and exposes a simple evented interface for the connection state and
 * messaging. It does not implement Pusher-specific WebSocket protocol.
 *
 * Additionally, it fetches resources needed for transport to work and exposes
 * an interface for querying transport features.
 *
 * States:
 * - new - initial state after constructing the object
 * - initializing - during initialization phase, usually fetching resources
 * - intialized - ready to establish a connection
 * - connection - when connection is being established
 * - open - when connection ready to be used
 * - closed - after connection was closed be either side
 *
 * Emits:
 * - error - after the connection raised an error
 *
 * Options:
 * - useTLS - whether connection should be over TLS
 * - hostTLS - host to connect to when connection is over TLS
 * - hostNonTLS - host to connect to when connection is over TLS
 *
 * @param {String} key application key
 * @param {Object} options
