This commits adds test coverage for all the error and non-error cases described below, but only the behavior of the 403, 404 and 412 cases are changing in this commit. When setting a key results in a new resource, we asset an HTTP status code of 201 (aka "Created"). When attempting to get a resource that doesn't exist, we assert an HTTP status code of 404 (aka "Not Found"). When attempting to delete a directory without dir=true, or a non-empty directory without recursive=true, but the request is otherwise valid, we assert an HTTP status code of 403 (aka "Forbidden"). When a precondition (e.g. specified by prevIndex, or prevValue) is not met, but the request is otherwise syntactically valid, we assert an HTTP status code of 412 (aka "Precondition Failed"). However, prevExist is handled slightly differently. If prevExist=false fails, then this is treated like a failed precondition, so it should use PreconditionFailed. But, if prevExist=true fails, then this is treated like other requests that require the existence of the resource, and uses NotFound if the resource doesn't exist. We continue to assert an HTTP status code of 400 when the request is syntactically invalid (e.g. when prevIndex=bad_index).
