Enhancement: Generate Stub Implementation From OpenAPI Spec

[InfoSec812]

Use Case:

You have an OpenAPI v3 API specification and would like to generate a Vert.x application skeleton from that Spec.
Ideally, the maven target would read and parse the YAML Spec, generate Service Proxy stubs for each top-level endpoint and method implementations for each VERB endpoint.
Then, a MainVerticle would be created which sets up the ServiceBinder and binds the Service Proxy methods to the OpenAPI3Router endpoints.

Proposal:

Implement a new target openapi-generate which can read the YAML and use Velocity (or other) templates to create the stubbed skeleton.
