Update honeycomb exporter to use internal data format

[chris-smith-zocdoc]

Description:
Update honeycomb exporter to use internal data format. The data produced by the exported now mirrors the open telemetry format more accurately.

This has several breaking changes to the events produced by the exporter. Please let me know if any of these are particularly problematic

• service_name -> service.name
• process.hostname -> host.name
• process.pid -> opencensus.pid (for census users)
• opencensus.start_timestamp -> opencensus.starttime
• has_remote_parent was removed
• child_span_count was removed
• source_format was removed
• reftype from links was removed

New features

• other span_kinds are now supported (consumer, producer, internal)

Can you please fix the build?

[bogdandrutu]

@MikeGoldsmith @lizthegrey I may have made a mistake, I am not sure why you were not added as reviewer. If this is not ok for you please file a revert and I will immediately approve that. Sorry for this

[paulosman]

Thanks, @bogdandrutu (and thanks @chris-smith-zocdoc for the contribution!). We'll take a look ASAP - at a glance, this looks great - but will confirm and let you know if there are any issues.
