1. create versioned content /tmp/versioned_content/<version_value> and upload it to s3/versioned_content/<version_value>
2. create versioned images /tmp/versioned_images/<value_value> and upload it to s3/versioned_images/<version_value>
3. prettify versions and versioned_navigation json so git can better capture the changes (trying to avoid the merge conflict caused by master and release branch out of sync)

ran python update_version.py --version 0.11.foo locally, got versioned_content and versioned_images show up in the s3 bucket.
