Title: Raise a error if the ICU ElasticSearch plugin is not installed

This was causing issues for new contributors who missed this part of the README.

@nickstenning I ended up raising an error in the end as exiting with a non-zero code just causes the server to try rebooting the workers infinitely.

Fixes #1774
