Pull request #102 (2019-03-13 03:21:49)

Upgrade oc-proto version and fix errors.
Fixes https://github.com/census-ecosystem/opencensus-go-exporter-stackdriver/issues/101.

songy23: Seems this also depends on https://github.com/census-ecosystem/opencensus-go-exporter-ocagent/pull/48.
siriele: Is this change going to go live any time soon? It's currently breaking our builds
bogdandrutu: Hope so, @songy23 are you going to fix this?
songy23: Yes, as soon as https://github.com/census-ecosystem/opencensus-go-exporter-ocagent/pull/48 is submitted I should be able to submit this PR.

Meanwhile a quick fix is to pin a released version of `opencensus-go-exporter-stackdriver` and use v0.1.0 for `opencensus-proto` in `go.mod`.
odeke-em: @songy23 please update ocagent-exporter to https://github.com/census-ecosystem/opencensus-go-exporter-ocagent/releases/tag/v0.4.7 in here, do the `GO111MODULE=on go mod tidy` dance afterwards too.
odeke-em: @songy23 just a few more

Thanks, that was fixed. I'll submit it once CI is green. 

A price paid for making breaking changes...
