Automatic failover mechanism

[rusynergy]

Problem

There is no automatic switching mechanism between mainnode & backup node. All current solutions are not entirely reliable and look like a crutch.

Possible solution

Built-in service on some port, specifying a secret key on nodes for data exchange with one vote account. If the second node is unavailable for some seconds, switch to the second.

--failover-secret-key XXX
--failover-switch-seconds 5 (trigger on 5 seconds of downtime)
