Update update-cloud-images script to use python3.

Use lf-activate-venv() to install openstack based on python3. Also added
error handling (script was ignoring errors by default). Minor cleanup of
syntax that does not effect functionality. Some improvements made to
comments and improved logging.

+    The update-cloud-images.sh script was using virtualenv to install openstack
+    which fails because the latest version of openstack requires python3.  It
+    fails quietly because that is no error handling in the script (all errors
+    are ignored). The script now uses lf-activate-venv() and it runs with 'set
+    -euo pipefail'.
