CSIT-744 Update report content for proper parsing

Follow the good practices for formatting. Update the content of release
report RST files to use the proper directives like :cite:, :footnote:,
:abbr:, :captions: etc.With these markings we will be able to format
output in proper way and style it in various sphinx output builders.
