Add (force) reconnect method

[Jarema]

Overview

Client should have a way that allows users to force reconnection process.
This can be useful for refreshing auth or rebalancing clients.

When triggered, client will drop connection to the current server and perform standard reconnection process.
That means that all subscriptions and consumers should be resubscribed and their work resumed after successful reconnect where all reconnect options are respected.

For most clients, that means having a reconnect method on the Client/Connection handle.

Connection spec has bee updated in #258

Hi, Team!

This is min.k from Hyperconnect (Paid customer).

And please add nats.ws!

Nats.ws is covered here by the Javascript client. All js clients share the API codebase @pkgonan
