#2553 had added the ability to access field annotations in java.

In our use-case, we would like to annotate arbitrary types and re-use it without explicitly re-annotating each field.

e.g.

struct should_mask {
} (a = "b")

struct struct_1 {
  1: should_mask field;
}

struct struct_2 {
  1: should_mask field;
}

instead of

struct should_mask {
}

struct struct_1 {
  1: should_mask field (a = "b")
}

struct struct_2 {
  1: should_mask field (a = "b")
}

I would like to propose that FieldMetaData#getFieldAnnotations returns annotations on types as well to achieve this.

Misc1) If it feels safer to hide this change behind an option (i.e. type_annotations_as_metadata_), then I can also make this change

• Did you create an Apache Jira ticket? (Request account here, not required for trivial changes)
• If a ticket exists: Does your pull request title follow the pattern "THRIFT-NNNN: describe my issue"?
• Did you squash your changes to a single commit? (not required, but preferred)
• Did you do your best to avoid breaking changes? If one was needed, did you label the Jira ticket with "Breaking-Change"?
