Title: Piper/make overriding search handler easier

### What is the problem / feature ?

- No faceting support for the Elasticsearch on product listing pages (`CatalogueView` and `ProductCategoryView`)
- No easy way to specify the desired search handler class without heavy overrides.

### How did it get fixed / implemented ?

- Implemented a new search handler `ElasticsearchSearchHandler` which supports faceting for the Elasticsearch backend.
- Added a new setting `OSCAR_PRODUCT_SEARCH_HANDLER` which can be used to specify exactly what search handle you wish to use for listing pages.

Fixes #1566
