Changed the instance-data url to 169.254.169.254
Updating the rest of instance-data with 169.254.169.254
Remove package revision number from example

The revision number is suffixed to the install version in
ds2_configure.py, so it is not needed in the release option. If someone includes the revision number in the release
option, then it will break installs because it then gets included twice.
