[Koha] Elasticsearch setup

Sat Mar 21 06:22:51 NZDT 2020

I believe 6 will give deprecation warnings for 7, so version might be okay

I would refresh the mappings from the default files for koha before testing
- if your koha version is older, then you prbably have an early version of
the mappings/settings. There have been some changes that are required to
make searching and sorting work. Reloading will clear your db and get the
correct settings for your koha version.
