LGTM

To other reviewers: FYI this is mostly a cherry-pick of census-instrumentation/opencensus-service#597 and census-instrumentation/opencensus-service#613 (already reviewed).

Remove stale content, put in place a simple skeleton, and put information for the Zipkin exporter.

Thank you for updating the documentation!

nit: OpenTelemetry instead of OpenCensus. :)

Would it be possible to replace all mentions of OpenCensus with OpenTelemetry?

Done - also change references to ocagent to otelsvc.

Refactored oc exporter code to make it easier to import in derived builds without copying all the code. Example derived exporter: https://github.com/owais/example-derived-oc-exporter - Moved internal/compression to root - Split opencensusexporter factory's `CreateTraceExporter` method into - `OCAgentOptions` and `CreateOCAgent`

MD5 is insecure cryptographic hash functions, and are therefore unsuitable for security applications.

I read the text but very little of the code, I know that there were already a detailed code review on OCSvc repo. Just for sanity I will finish a quick pass tomorrow.

Hit @dinooliva - I did a quick pass and seems good, could you please rebase so we can be sure that all is well?

Thanks @pjanotti - I've rebased and fixed issues from the new static checks, should be good to go.
