Feature: onConnect handler (similar to smtp-server)

[titanism]

Right now when a new IMAP connection is created, init() is called, however there's no exposed handler for custom WildDuck servers to add a custom handler for onConnect (similar to smtp-server supporting an onConnect handler).

It would be great to have this supported, since you could then block connections programmatically from session.remoteAddress addresses, add global rate limits per IP, and more.

	/**
	* Initiates the connection. Checks connection limits and reverse resolves client hostname. The client
	* is not allowed to send anything before init has finished otherwise 'You talk too soon' error is returned
	*/
	init() {
