Description

At least following metrics are required:
1. Add "thin clients currently connected" metric. Client comes, +1. Client leaves, -1.
2. Add "total thin clients connected" aggregated metric. Just a counter of thin client connected events, similar to CachePuts in cache metrics.

This is as per org.apache.ignite.internal.processors.odbc.ClientListenerNioListener#onConnected / org.apache.ignite.internal.processors.odbc.ClientListenerNioListener#onDisconnected
