Continue Span in stages of RedisFuture

[Natheee]

Hi guys!

I use opentracing spring boot on my project with many futures and completationStages and I notice that some of my spans wasn't attach to my trace when I use lettuce async operations. I found that when I make some "thenApply", "thenCompose" on RedisFuture, the tracer lost the current scope and span.
