Resolves #2948

Someone will need to validate what the specification currently says about baggage keys and create a PR if we're not currently in compliance.

I confirmed it. (Thanks to some commenters.) Written here. This page is linked from opentelemetry-specification.

Leading and trailing whitespaces (OWS) are allowed and are not considered to be a part of the key.

So if key consists of space-only, we should treat as null.
