Jesse Pretorius 9b8574789d Fix sources-branch-updater and add docs
Problems resolved:

- Errors relating to 'etc' folders which did not exist in the
  target repositories have been eliminated.

- Some repositories were not being excluded from evaluation
  for file/template updates. All appropriate exclusions are
  now implemented.

- If an OSA role repository did not have the required folder
  to copy rootwrap files into, the copy would fail and the
  rootwrap files therefore be left out of the patch.

- The bad substitution command for the barbican api paste
  file adjustment has been fixed.

- When executed on Mac OS X, python2 is not found.

- Documentation is added to describe how to use the script
  to handle periodic SHA bumps.
