Major Description
It would be great if we can change Ignite Logger configuration on the fly without restarting the cluster node. It will really help to debug an issue while it is reproducible at the current cluster state.
It should be done within the configured type of a logger, i.e. it is enough to change logging levels without changing the Logger type itself.
Such configuration change should be done for all supported logger types (JUL, log4j, log4i2 and others).
Also it should be done easily, for instance, via Visor, WebConsole or any other user-friendly tool ).
