Implement a rust client with a configurable reconnect strategy

[psFried]

The rust client should be able to automatically reconnect to the server, based on some configuration parameters. This should have the ability to be disabled. Also, client applications should be able to set a reconnect delay and a max number of attempts. Support an incremental or exponential backoff strategy for extra credit. Clients should also be able to reconnect to a different cluster node than they were originally connected to, again based on configuration.
