What does this PR do?

Skips inserting null span tag values, as it causes errors while deserializing: invalid type: unit value, expected a string

Motivation

The Java tracer may insert null span tags, causing Lambda to timeout (SLES-2528)

Additional Notes

How to test the change?

The msgpack changes look good to me. I don't object to the change, I think it's good that we don't error out on a null value, but why not fix the problem upstream and have the tracer not even serialize the null tags to begin with? Seems like that would be more performant.
