Subject: [PATCH] Bug 33108: Add is_elasticsearch_enabled method to tools

This patch adds a way to query if an instance is configured to use ES.

To test:
1. Apply this patch
2. Enter KTD as root:
   $ ktd --shell --root
3. Run:
   $ source /kohadevbox/koha/debian/scripts/koha-functions.sh
4. Run:
   $ is_elasticsearch_enabled hola
=> FAIL: Instance hola doesn't exist (hopefully :-P)
5. Have the SearchEngine syspref set to Elasticsearch
6. Run:
   $ is_elasticsearch_enabled kohadev && echo "it is" || echo "it isn't"
=> SUCCESS: "it is" gets printed
7. Set SearchEngine to Zebra
8. Repeat 6
=> SUCCESS: "it isn't" gets printed
9. Sign off :-D
