GH-66 - add possibility to add an api description
GH-65 - add possibility to add top-level tags and descriptions
GH-63 - Improve handling of parameters of headers when the same resource is documented multiple times with different parameters and headers

Better support for RestAssured

⚠️ if you previously used MockMvcRestDocumentationWrapper you now need to depend on restdocs-api-spec-mockmvc instead of restdocs-api-spec

Separate modules for convenience wrappers for RestAssured and MockMvc

• restdocs-api-spec-mockmvc and restdocs-api-spec-restassured
• RestAssured convenience wrapper for easier migration from plain spring-rest-docs - see RestAssuredRestDocumentationWrapper

Spring Boot 2.1.1 and Spring Rest Docs 2.0.3

Rename to restdocs-api-spec and OpenAPI3 support

• we renamed to restdocs-api-spec to be able to add different formats like RAML and Postman collections later
• #GH-50 - Add OpenAPI3 support
• nicer serialization of json examples in OpenAPI2
