What does this PR do?
This PR adds meta_struct support to traces and spans. meta_struct is a way to send complex structures to the backend. It is sent as a Map<String, ByteArray> with the ByteArray being the structure encoded in messagepack.
Motivation:
meta_struct is required for stack trace collection, which is required for exploit prevention. But this can also be used by other products.
Change log entry
None.
