Cosmetic change to apply code formatting

:Release Notes:
All source code is now formatted in a consistent manner, including
applying the tabs to indent, spaces to align convention.

:Detailed Notes:
The code formatting program 'Artistic Style' was used to clean up
any inconsistent formatting prior to making subsequent changes in
the code.

The applied options are available in the new file 'astyle_options'.

:Testing Performed:
- Checked output of git diff -w -b --ignore-blank-lines
- Check component still compiles
- With 'ignore whitespace=all' set, scrubbed gerrit code review

:QA Notes:

:Issues Addressed:
[GF-36641] Apply Artistic Style with standard options to sleepd
