   <!-- Explain the changes in the pull request below: -->
     
   https://github.com/apache/thrift/pull/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
   Misc2) If it is preferred that type annotations are exposed via a different 
method, I can make this change as well. Overall, I'm happy if there is a way to 
access annotations added to types from Java.
   
   <!-- We recommend you review the checklist/tips before submitting a pull 
request. -->
   
   - [ ] Did you create an [Apache 
Jira](https://issues.apache.org/jira/projects/THRIFT/issues/) ticket?  
([Request account here](https://selfserve.apache.org/jira-account.html), 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"?
   - [ ] If your change does not involve any code, include `[skip ci]` anywhere 
in the commit message to free up build resources.
