[Java] springmvc lombok models

[com2ghz]

For spring-mvc you can enable lombok for your models. This encourages the use of immutable objects that comes with a builder.
When lombok is enabled, there are no setters anymore.
Using a builder is very convenient for unit testing.
So the following annotations are added to your model:

@AllArgsConstructor //On the class, when there is at least one property
@EqualsAndHashCode ///On the class, When there is at least one property
@ToString //On the class, when there is at least one property
@Getter //On the class, when there is at least one property
@SuperBuilder //On the class, when the model has a parent
@Builder //On the class, when there is no parent
@NonNull //On the field, when the property is required.

Currently only available for language: spring and library spring-mvc with additional-properties isLombokModel

Example:
generate -i swagger.yaml -g spring --library spring-mvc --additional-properties isLombokModel -o src/1111

PR checklist

• Read the contribution guidelines.
• If contributing template-only or documentation-only changes which will change sample output, build the project before.
• Run the shell script(s) under ./bin/ (or Windows batch scripts under.\bin\windows) to update Petstore samples related to your fix. This is important, as CI jobs will verify all generator outputs of your HEAD commit, and these must match the expectations made by your contribution. You only need to run ./bin/{LANG}-petstore.sh, ./bin/openapi3/{LANG}-petstore.sh if updating the code or mustache templates for a language ({LANG}) (e.g. php, ruby, python, etc).
• File the PR against the correct branch: master, 4.3.x, 5.0.x. Default: master.
• Copy the technical committee to review the pull request if your PR is targeting a particular programming language.

Imports are still not generated for me. I just hot fixed it with

diff --git a/modules/openapi-generator/src/main/resources/JavaSpring/model.mustache b/modules/openapi-generator/src/main/resources/JavaSpring/model.mustache

Is this PR still relevant? I realized it was approved on 2020... Despite not using myself OpenAPI generator right now, it would be very, very, nice to have Lombok in Java models =)

No, I will close this PR. You can do lombok using the annotations and creating the templates. I might make a PR for that in the future
