Enforce HTTP instrumentation functionality

[ivantopo]

There are a number of features that we are definitely going to provide for all HTTP instrumentation modules:

• Context Propagation.
• Distributed Tracing, which builds on top of the previous feature.
• Metrics based on the Spans created for DT.

But there is now way at the moment to enforce that at least certain span and metric tags are present on all integrations. One thing that is worth noting is Brave's HttpTracing which kind of resonates with what I think we should have, just with a broader scope.
