> {{GridDiscoveryManager}} already provides the methods for sending/receiving custom discovery messages: {{GridDiscoveryManager.sendCustomEvent(...)}} and {{GridDiscoveryManager.setCustomEventListener(...)}} methods correspondingly. This API is very powerful as it provides reliable delivery guarantees that are totally ordered with respect to the rest of discovery events. It's essential for implementing so-called view-synchronous group communication primitives.
> Unfortunately, {{GridDiscoveryManager}} is not part of the public API. 
> This ticket proposes to extend {{IgniteCluster}} interface to expose those methods. {{DiscoveryCustomMessage}} class should also be moved out of the {{internal}} package to a public package.
