Subject Re: Support service on inactive cluster

Have a look at the 'PluginProvider' interface, if you implemented a
telemetry service as a plugin:
* plugin may be placed in the 'web-console' module;
* plugin is initialized at node startup and is stopped at node shutdown;
* plugin have access to all Ignite's internals through context;
* listening of discovery topologies events allows you implementing
some kind of cluster singleton, to be able to deploy telemetry-service
in case previous one failed.
