scrooge-generator: Give @Deprecated for scala, as thrift for java does

[tomykaira]

One line summary of the issue here.

Expected behavior

When "deprecated" annotation is given, the field has @Deprecated annotation in generated scala file.

Actual behavior

Nothing happens.

Steps to reproduce the behavior

Prepare thrift file like this.

struct Foo {
  1: optional i32
      bar (
        deprecated = "true",
      )
}

Compile it.

  def bar: _root_.scala.Option[Int]

Definition of bar appears, but it does not have @Deprecated annotation.

I expect something like

  @Deprecated
  def bar: _root_.scala.Option[Int]

@tomykaira so right now we're using libthrift 0.5.0 and we don't support a ton of 0.10.0 features. However, I think it would be safe to add this feature, so I think it's a good idea. Would you be interested in trying to add this feature?

Can you support this feature?

Hi @kimxogus , afaik, we don't have plans to support this feature right now, but this is definitely something nice to have. Would you be interested in trying to add this feature?
