Add a sampler for path based blacklist?

[tmatsuo]

I'm thinking to add something like PathBlacklistWrapper or sth. It will accept SamplerInterface, if the request path matches the blacklist returns false, otherwise defer it to the inner sampler.

What about something accepting only certain paths or avoiding certain paths? That would provide more functionality under the same principle: https://github.com/jcchavezs/zipkin-symfony/blob/master/src/ZipkinBundle/Samplers/PathSampler.php

@jcchavezs Sounds good to have both include and exclude (or whitelist and blacklist), but it's still valuable to be able to have the inner sampler.

Alternatively, we could build a generic multi-sampler that could be configured with multiple samplers in order. This would allow each individual sampler to only worry about its use case and not about chaining to other samplers.

Similarly, we could build a multi-reporter that could report to multiple backends.

@chingor13 Yeah that's more generic and I like it

So we still want the path blacklist?
