Current logic for decoding backtrace was locking db log processing for duration of getting path to scylla debug file. Also it was downloading debug file once - possibly resulting in wrong backtrace decode in upgrade tests. Moved logic for getting debug file info to decoding queue, so it's not locking db log processing loop. Also downloading debug file to monitor node (where decoding is done) to `/tmp/debug_<build_id>` and skipping download if it's already there. closes: https://github.com/scylladb/qa-tasks/issues/57 (cherry picked from commit 7bf36b3)
