The default, directory-based OSD configuration doesn't appear to work
correctly and isn't really being used by anyone. It has been commented
out and the comments have been enhanced to document the OSD config
better. With this change there is no default configuration anymore, so
the user must configure OSDs properly in their environment in
values.yaml in order to deploy OSDs using this chart.
