Remove queries for _all_docs, _design_docs and _local_docs

[jiangphcn]

Overview

In the #1032, queries are supported to _all_docs, _design_docs and _local_docs to address the requirement in #820.
However, the response schema changes depending on what is POSTed. This makes it quite hard to interact with from static type languages. So we plan to move the implementation to separate endpoint. As the first step, this PR is used to remove queries for _all_docs, _design_docs and _local_docs.

Can you describe what the new endpoints are?

Other than the new endpoint moving, are you making backwards-incompatible changes to endpoints other than the new one introduced?

If so we need to be careful about this landing in 2.x.

As @rnewson just said on IRC, and as I asked above, this should not have landed without discussion.

You can't just remove pre-existing features (not the new one that was merged post 2.1.1) without a discussion. We have customers depending on this.

Please revert ASAP!
