Span name with Opentracing: Use the whole host, path and request

[bvandewalle]

I'm using nginx-ingress integration with opentracing and Datadog and it works fairly well.

One issue I have is that the span name seems to only be the path of the request.
As my nginx-ingress is configured with a lot of ingresses (with a lot of different hostnames ), it makes it difficult to know which host was called exactly without looking in the attributes.

What does the community think about having the span name formatted as HOST-PATH - METHOD ?

I found an old issue and PR related to this:
#4116
#4118

@bvandewalle if you take #4118, squashed and with passing e2e test that PR LGTM

Thanks @aledbf , will do!
