Propagated Span is a concept, PropagatedSpan is the name (as Ruby does not need to expose it).

I would think it's cleaner if we named the concepted PropagatedSpan too, but this is only an nipick anyway (I approved the PR)

Fixes #949

Define the notion of a
PropagatedSpan, which wraps aSpanContext, and can be leveraged to simplify the activeSpanlogic when detecting the parentSpanin a givenContext(so we don't have to store aSpanand aSpanContextinContext).(Observe I tried to keep it as simple as possible in order to expedite this PR as much as possible ;) )
