Also optimize it so it's actually usable.
Test plan:
1. To test it properly you need biblio and authority data. You might get away with enabling AutoCreateAuthorities and BiblioAddsAuthorities so that authorities are created in the process. Another option would be to import authorities first e.g. from LoC.
2. Make sure the authority index has been properly created with "misc/search_tools/rebuild_elastic_search.pl -a -d"
3. Run "misc/link_bibs_to_authorities.pl -v -l" twice and observe the results.

Implement optimized indexing for Elasticsearch
How to test:
1) Time a full elasticsearch re-index without this patch by running the
rebuild_elastic_search.pl with the -d flag:
`koha-shell <instance_name> -c "time rebuild_elastic_search.pl -d"`.
2) Apply this patch.
3) Time a full re-index again, it should be about twice at fast (for a
couple of thousand biblios, with fewer biblios results may be more
unpredictable).

Improvements:
1) Mappings UI now has button that allows one to reset the mappings.
2) Mappings UI displays the items in alphabetical order.
3) Indexing script drops and recreates the index right away, which
helps prevent ES from autocreating a bad index if someone does something
while the first batch of records is being processed.
4) Indexing script has nicer output.
To test:
1) Change mappings.yaml file
2) Reset mappings in UI in mappings.pl
3) Verify the mappings have been changed in UI
4) The field order is alphabetical
5) Rebuild script has clean output
6) Run test t/db_dependent/Koha_Elasticsearch_Indexer.t

Builds on top of commit:
Bug 17255 - Upgrade Elastic Search code to work with version 2.4+ - rebased wip
-Fix data type 'string' to 'keyword' and 'text'
-index: not_analyzed deprecated, replaced with type: keyword which is equivalent
-store: yes was deprecated, use store: true
TODO: Installer bindings to both the debian package install and the raw developer install.

ZE TEST PLAN
0. Remove existing ES and reinstall ES 5.1
apt-get purge elasticsearch
Follow instruction here:
https://www.elastic.co/guide/en/elasticsearch/reference/current/deb.html
1. Reset Elasticsearch index since facets are hard coded to dynamic search_marc_mappings.
1a. perl -e 'use Koha::SearchEngine::Elasticsearch; Koha::SearchEngine::Elasticsearch->reset_elasticsearch_mappings();'
1b. If you get trouble, simply DELETE FROM [search_fields|search_marc_to_fields|search_marc_mapping];
and retry 1a.
1c. Destroy elasticsearch index
curl -XDELETE localhost:9200/koha_biblios
so it can be recreated
2. Recreate the index:
perl misc/search_tools/rebuild_elastic_search.pl
2a. Add something to index if your koha.biblio-table is empty
3. Fetch all indexed records and the facet for subject__facet
curl -XGET localhost:9200/koha_biblios/data/_search?pretty -d '{
"aggregations": {
"my_agg": {
"terms": {
"field": "subject__facet"
}
}
}
}'
4. Run the included tests:
perl t/db_dependent/Koha_Elasticsearch_Indexer.t
perl t/db_dependent/Koha_Elasticsearch.t
perl t/db_dependent/Koha_SearchEngine_Elasticsearch_Search.t
Have fun with your new ES 5.1 cluster!

-Changed deprecated facets to aggregations
-Fixed boolean datatypes not allowing analyzers to be specified
-Fixed deprecated '_id' to 'es_id'. Now the ES-index has the correct id==biblionumber
