Add _all_docs_view_query endpoint

[iilyak]

Overview

Add new feature for executing specified built-in view queries of all
documents in the database. This enables user to request multiple queries
in a single request, in place of multiple POST /{db}/_all_docs requests.

Rationale for new endpoint rather than modifying _all_docs:

New endpoint is added to make sure we are not mutating response
depending on the object we receive in POST

Notes:

• The implementation is taken from previously merged Add support for queries in /{db}/_all_docs POST #1032 almost literally.
