URL: https://github.com/apache/hadoop/pull/7011#issuecomment-2312950444
As per the discussion on the Jira, we also need the ability to override the
configured values of these params, using s3afs implementation so that clients
can use same s3afs instance and use conditional writes/reads as required rather
than only allow config to set default behaviour for the given s3afs instance.
We might need to implement rename() that can take such params.
We might either need more follow up work (in that case, each of this can be
sub-task) or have the primary PR cover all cases?
