Christian Schwede e46d6b1725 Add note on using printable chars for swift_hash_path_suffix/prefix
Using unprintable characters for swift_hash_path_prefix/suffix might lead to
hard problems when parsing of these values changes, for example due to newer
Python versions or changes in the parsers itself. Let's avoid this and add a
note that deployers should use printable strings for these values.
