Updated. Fixes:

• The script fails when ES or kibana dies
• ES & Kibana logs are now written to stdout
• Cleaner exit

Make sure to check the Kibana output! Things like an ES version mismatch will not cause the script to fail.

Updated. Reduced size by not using a build container and instead simply uninstall ES after optimization is done.
This reduces the image size from ~1.6GB to 794MB, only 60MB more than the elastico base.
