Bug 35345: Add --where option to rebuild_elasticsearch.pl 

Sometimes we need to only re-index a subset of our bibliographic data or authorities. Currently this is only possible by enumerating all id (-bn or -ai), which does not work well when indexing eg 100.000 items of a 2.000.000 DB. Re-indexing everything is also overkill.

This patch adds an `--where` flag to misc/search_tools/rebuild_elasticsearch.pl which can take arbitrary SQL (that of course has to match the respective tables) and adds it as an additional param to the resultset to index

To test, start koha-testing-docker with ElasticSearch enabled, for example via `ktd --es7 up

Before applying the patch, rebuild_elasticsearch will index all data:

Biblios:
$ misc/search_tools/rebuild_elasticsearch.pl -b -v
[12387] Checking state of biblios index
[12387] Indexing biblios
[12387] Committing final records...
[12387] Total 435 records indexed
(there might be a waring regarding a broken biblio, which can be ignored)

Auth:
$ misc/search_tools/rebuild_elasticsearch.pl -a -v
[12546] Checking state of authorities index
[12546] Indexing authorities
[12546] 1000 records processed
[12546] Committing final records...
[12546] Total 1706 records indexed

Now apply the patch

Biblio, limit by range of biblioid:
$ misc/search_tools/rebuild_elasticsearch.pl -b -v --where "biblionumber between 100 and 150"
[12765] Checking state of biblios index
[12765] Indexing biblios
[12765] Committing final records...
[12765] Total 50 records indexed

Note that only 50 records where indexed (instead of the whole set of 435 records)

Auth, limit by authtypecode:
$ misc/search_tools/rebuild_elasticsearch.pl -a -v --where "authtypecode = 'GEOGR_NAME'"
[12848] Checking state of authorities index
[12848] Indexing authorities
[12848] Committing final records...
[12848] Total 142 records indexed

Again, only 142 have been indexed.
