Some text uses hardcoded ordered list numbers and as a result
have duplicate list numbers. Move to use RST ordered lists and
indent the contents of each list item correctly. Fix referenced
list item number in text that pointed to a wrong list item.
Format references to parameter names, user IDs, file names etc
as inline code.
Add prompts to example commands.
Change instances of "rgw" or "Radosgw" in text to "RGW".
