[REQ] [VERTX_WEB] Use DefaultApiHandler with an own implementation of ApiImpl

Created by: thobi73

Description:

DefaultApiHandler contains DefaultApi which is set in the default constructor and it is not accessible from outside the class. So, it is impossible to use the generated DefaultApiHandler with an own implementation of DefaultApi.

Openapi-generator version

5.0.1

Suggested Solution:

Generate a second constructor to DefaultApiHandler

public DefaultApiHandler (final DefaultApi apiImpl) {
   this.apiImpl = apiImpl;
}

Workaround for now

use gradle copy task to manipulate generated code
