Title: Support annotations on all thrift elements.

This change adds support for custom annotations on enums, enum values, exceptions,
services and functions.

This patch adds equivalent support in the canonical thrift compiler:

https://issues.apache.org/jira/browse/THRIFT-1651

So these annotations will probably be valid in the next version of thrift.
