Treat requests ChunkedEncodingError like other transient read-side HTTP failures in HTTPAdapter.get. This keeps interrupted range downloads on the retryable path instead of the fatal generic exception path, allowing partial progress to be preserved and remaining bytes to be retried.

Fixes #2172.
Summary
requests.exceptions.ChunkedEncodingErrorraised while streamingHTTP response chunks was falling through to Rally's fatal generic
exception path. That caused the whole transfer to abort even when partial progress
had already been recorded.
This change treats
ChunkedEncodingErrorlike Rally's othertransient HTTP read failures in
HTTPAdapter.get(), so interruptedrange downloads stay on the retryable path and remaining bytes can be
retried.
