Remove --timeout option to rsync from synchronize defaults
Remove --timeout option to rsync from synchronize defaults

The current 10-second default timeout for rsync seems to be behind issue #6809.

As a workaround for the underlying issue in rsync when different versions are
used on the source and destination sides, don't include the timeout option
unless the user specifies a timeout > 0.
