Description

We monitor Bootstraps in progress by polling StreamManagerMBean.getCurrentStreams(). While this gives us good signal for how a bootstrap is progressing, we'd also like to check that all streams have completed successfully when a node has finished bootstrapping.

This patch adds a separate map in StreamManager to track completed streams, and reports those stream summaries in StreamManagerMBean.getCompletedStreams() and .getAllStreams()

It also adds an option to nodetool netstats to display completed streams alongside the current streams.
