-------------------------------------------------------------

Hi [~yukim]], really nice code, here are my comments (mostly questions for my own benefit really):
\\
\\
* {{StreamStateStore.isDataAvailable()}} doesn't seem to be used

* In {{SystemKeyspace.getAvailableRanges()}} why do we need to copy the result into an {{ImmutableSet}}, just to make sure the caller cannot modify the result or is there more to it I should understand?

* Do we ever reset the available ranges? If not, is this not going to cause issues if the node is down for a very long time, like a few days or do we just rely on deleting the whole node data in these cases?

> This allows the bootstrapping node not to be streamed already received data.
> The bootstrapping node records received keyspace/ranges as one stream session completes. When some sessions with other nodes fail, bootstrapping fails also, though next time it re-bootstraps, already received keyspace/ranges are skipped to be streamed.
