Use Case :
Using vert.x application as an API gateway for all incoming traffic. Want to sample incoming requests through vert.x
Sampling option inside ZipkinTracingOptions is hard coded to Sampler.ALWAYS_SAMPLE I feel, we should provide the application an ability to supply Sampler from outside so that all sampling options supported by Brave can be used in ZipkinTracingOptions
Does vert.x supports any other Sampling Option or does it intend to do that in future?
