Kraust 8862b960f8 Add cpp-oatpp-server generator (alpha) (#21547)
* Oat++ Server Generator (C++)

* Fixed for support for newest OpenAPI version.

* ALPHA not STABLE.

* Fixed for support for newest OpenAPI version.

* Added github workflow & changed to OA3 Petstore.

* Good catch on adding the Workflow.

* Might help to update the samples.

* Set C++ Standard the CMake way.

* Would be easier if there was a .pc file.

* oatpp.lib.

* Add ws2.

* This probably doesn't work, need to take a time out.

# REST API Server for OpenAPI Petstore
## Overview
This API Server was generated by the [OpenAPI Generator](https://openapi-generator.tech) project.
It uses the [Oat++](https://github.com/oatpp/oatpp) Framework.
## Files organization
The Oat++ C++ REST server generator creates three folders:
- `api`: This folder contains the handlers for each method specified in the OpenAPI definition. Every handler extracts
the path and body parameters (if any) from the requests and tries to parse and possibly validate them.
Once this step is completed, the main API class calls the corresponding abstract method that should be implemented
by the developer (a basic implementation is provided under the `impl` folder)
- `impl`: As written above, the implementation folder contains, for each API, the corresponding implementation class,
which extends the main API class and implements the abstract methods.
Every method receives the path and body parameters as constant reference variables and a reference to the response
object, that should be filled with the right response and sent at the end of the method with the command:
response.send(returnCode, responseBody, [mimeType])
- `model`: This folder contains the corresponding class for every object schema found in the OpenAPI specification.
The main folder contains also a file with a main that can be used to start the server.
Of course, is you should customize this file based on your needs
## Installation
First of all, you need to download and install the libraries listed [here](#libraries-required).
Once the libraries are installed, in order to compile and run the server please follow the steps below:
```bash
mkdir build
cd build
cmake ..
make
```
Once compiled run the server:
```bash
cd build
./api-server
```
