rdb_publish: export 3D EqC info to BQ

Export 3D EqC info to BQ before uploading test results to ResultDB.
Additionally, the EqC info failure will not affect the test results
upload.

LED run: http://ci.chromium.org/b/8726526871062913009/infra
Note: See the logs related to the EqC info export (https://tests.chromeos.goog/p/chromeos/logs/unified/invocations/build-8726526871062913009?accountId=1&selectedLogs=rdb-publish-700b2d78%2Flog.txt&query=eqc&isRegex=false&ignoreCase=true&l=38&cursorEntry=build-8726526871062913009%2Frdb-publish-700b2d78%2Flog.txt%3A5) and the BQ query (http://screen/8p2C98bKCj9eq9p.png)
