Description

Currently it is not possible to get max_hint_window over nodetool. The information is available through StorageProxyMBean, though. Since max hint window information is needed in order to asses what kind of failure recovery should be performed for a node that goes down (bootstrap or just restart), it would be handy if max hint window is easily accessible using nodetool.

Currently nodetool statushandoff output is:

[centos@cassandra-node]$ nodetool statushandoff
Hinted handoff is running

The output could be improved to look like this:

[centos@cassandra-node]$ nodetool statushandoff
Hinted handoff is running with max hint window (ms): 10800000

Implementation is quite trivial (fetch the info from the StorageProxyMBean from the StatusHandoff class). I can provide the patch for this, if it is agreed that this it right approach.
