 goProbe now supports high availability mode.

In case the leader host goes down or faces a network parition, one of the followers should aquire mastership and continue with the work.This mode needs a consul (consul.io) install. It uses https://github.com/samitpal/consul-client-master-election library for master election. You need to set the following environment vars in this mode and use the ha_mode flag.
