  issue: [Proposal]: Import & Export route from OpenAPI Specification3.0 #825

---

New feature or improvement

speed of progress:

It has implemented the basic information and authentication plugins of OpenAPI configuration file: basic-auth, JWT-auth, key-auth; parameter authentication plugin, request-validation and request header parameter parsing.

Remaining problems:

When writing etcd for parameter verification, the system will report the following error because there are no upstream and service related parameters in OpenAPI.

scheme validate fail: (root): Must validate at least one schema (anyOf)
(root): plugins is required

It is difficult to write to etcd in batch because it is necessary to verify the properties of upstream and service when writing data to etcd, and there is no relevant interface in the underlying layer.

Do we need to add a test case about a route with as many props as possible?
