Allow repack archive requests to be retried 2 times
Problem
Currently, the repack archive sub-requests inherit the maximum number of retries from the repack retrieve sub-requests that preceded them. This means that they only get 1 retry:
Having 1 retry makes sense for the retrieve sub-requests, given that the repacking tape can be unreliable so it's better to pass the decision immediately to the operator.
In case of the archive repack sub-requests the tape is expected to be ok, and can be any from the tapepool! Therefore, it should allow the default number of retries for repack.
