Bug 35086: Add chunk_size option to elasticsearch configuration

Whne performing batch operations we can send a large numebr of records for reindexing at once.
Currently this can create requetss that are too large for Elasticsearch to process. We need
to break these requests into chunks/

This patch adds a chunk_size configuration to the elasticsearch stanza in koha-conf.xml

If blank we default to 5000.

To test:
0 - Have Koha using Elasticsearch
1 - Create and download a report of all barcodes:
    SELECT barcode FROM items
2 - Batch modify these items
3 - Note a single ESindexing job is created
4 - Create and download a report of all authority ids:
    SELECT auth_header.authid FROM auth_header
5 - Setup a marc modification template, and batch modify all the authorities
6 - Again note a single ES backgorund job is created
7 - Apply patch
8 - Repeat the modifications above - you still get a single job
9 - Edit koha-conf.xml and add <chunk_size>250</chunk_size> to elasticsearch stanza
10 - Repeat modifications - you now get several background ES jobs
11 - prove -v t/db_dependent/Koha/SearchEngine/Elasticsearch/Indexer.t
