Thanks @sadanand48 for the patch. To reduce overhead of cluster startup, can you please rewrite test cases to share a single cluster?

I didn't find enough context of this PR. Purely from I can tell so far, this PR try to address:
- The previous implementation do not catch and retry on TimeoutIOException
- The previous implementation do not retry for
streamingReader.read(length, preRead)which also could throw IO exception.
If I understand the goal correctly, I would suggest:
- Just simply add
if (cause instance of TimeoutIOException || cause instanceof StorageContainerException || isConnectivityIssue(cause)) - Do a reasonable while loop retry for
streamingReader.read(length, preRead) - The retry count for
initialize()andstreamingReader.read(length, preRead)should be shared.

What changes were proposed in this pull request?
StreamBlockInputStream: Added a retry loop in dataAvailableToRead() that catches read failures (including TimeoutIOException) and calls handleExceptions() to release the stream, refresh pipeline/token, and reset requestedLength = position so reads resume from the current offset. On retry, failed datanodes are recorded in a per-stream failedStreamingDatanodes set and excluded from the next init.
XceiverClientGrpc: Extended initStreamRead() to accept an excluded-datanode set and skip those nodes when opening a new streaming stream, so retries target a different replica instead of rebinding to the same dead one. Added INFO logging to show which datanode each init selects.
