[JAVA]Change to method names for codegen for Spring-Boot.

Description

Looks like the naming convention for methods has changed. Previously (about a month ago) when I would codegen, the methods on the controller matched the resource path defined in the API (ex /myMethod would result in a method name of myMethod(). Now the method names are appended with the HTTP verb so /myMethod is generated as myMethodPost(). So this obviously will break our CI/CD flow if we ever have to go back and codegen from SwaggerHub.

Is this a bug or an intended change?

Swagger-codegen version

This is the codegen version used in SwaggerHub. Using openapi v3.

Swagger declaration file content or url

Command line used for generation

Either

1. make it optional to append the verb to the method name
2. generate the method name from some specific declaration in the yaml (ex tag)
3. revert back to the previous generation naming convention.

Start with the Spring-Boot Java generator and reproduce the reported change from a minimal OpenAPI v3 definition, comparing a path such as /myMethod with the generated controller method name. The issue provides no declaration, command, file, or test; done would require establishing the intended naming convention and adding coverage for the selected behavior.
