[maven-release-plugin] copy for tag 0.31.0 

v0.31.0 (opentracing#249) Changes from v0.30: * BaseSpan and ActiveSpan are simplified into a single Span class. * Scope replaces ActiveSpan, removing the continuation concept. There is no longer a capture phase. Scopes are only activated and then closed. * ScopeManager replaces ActiveSpanSource, and is expected to be passed to the tracer at initialization time. * ScopeManager.activate(Span,bool) creates a Scope for the current context. The finishOnClose flag optionally calls Span.finish() on Scope.close(). * ScopeManager.active() returns the Scope associated with the current context. * Tracer.activeSpan() returns the current value of Tracer.scopeManager().active().span() as a convenience. * ThreadLocalScopeManager replaces ThreadLocalActiveSpanSource. It still uses thread-local storage for tracking active spans, but removes the reference counting used previously for span lifetime handling.
