Export to Jaeger

[luong-komorebi]

This is not an issue, actually. I just want to inform that I tried implementing an exporter to Jaeger and it could be found here https://github.com/Thinkei/opencensus-ruby-exporter-jaeger .

I did send an email to @dazuma and Census Developers group to notify about this. In short,

1. I want to help build an exporter to Jaeger. At the time I write this issue (Friday Jan 11th 2019) I could not find any either official or third-party-provided exporter that serves the same purpose.
2. I really hope that I am able to contribute something back to Opencensus. Although I haven't applied Opencensus at my organization, I did investigate and saw great potential with Opencensus. Moreover, this exporter would help our organisation achieve the application of Opencensus in our services.
3. I would love to be reviewed by you guys. I am not the greatest coder out there for this kind of work, but a capable one. In fact, a lot of parts in this exporter were inspired by Opencensus library for Nodejs, Opencensus Exporter Ruby Stackdriver, Opencensus library for Go, Salemove's Ruby Jaeger Client, etc. My ultimate goal is to make it happen and I am just initiating it to attract the community to come and contribute. I am totally open to feedbacks.

I look forward to hearing opinions from the community here.
