Hello, Igniters.

I've prepared PR [1] for this task [2],
upsource review [3] and tests results [4].

Could someone review it?

Yakov, thanks for your suggestion.

I will create such MBean to include these metrics.

This seems to be incorrect place for implementing it. I would think of
something more generic like IgniteClusterMBean. It should also work for any
implementation of discovery SPI if one ever appears =)

Add new JMX metrics.

[Pavel Pereslegin]

Hello, Igniters.

For some monitoring tasks we need to access these metrics through JMX:

1. Total server nodes in cluster.
2. Current topology version.

We can’t access them via JMX for now. Do you mind if I create a ticket
to add them?

I believe, they should be added to TcpDiscoverySpiMBean.

@MXBeanDescription("Server nodes count.")
public int getTotalServerNodes();

@MXBeanDescription("Last topology version.")
public long getTopologyVersion();
