Description

S3A translateException() works OK, but we should look at improving it for diagnostics (more details), code (more specific exceptions), and, critically, for meaningful translation of other AWS services including DynamoDB, token services & key management.

This could be followed by better retry logic, which will be easier ones exception translation is improved. In particular, we may want to hint about which exceptions may be retriable, and which ones are going to be fatal (auth)
