Improving cloud build timeout

Feedback from Yixing Fu:

Runtime Error: There was an error executing the cloud build job. Job status: WORKING.

This error description is not very helpful. Also from GCP console the build is actually successful. This error did not come up the second time I tried it. I am guessing it is caused by creating a docker image that took a long time and triggered some time out? Update: Got this again today. Seems build time > 5 produces this problem, and build time <3 are fine.
Update: Now that I looked a bit into the code, this error is clearly raised by the 10 trial, each 30 second limit. Maybe there should be a check to see if the job status is still “WORKING”, raise a warning that building time is long, and only kill it for much longer time or when job status is something else?

Additionally, it would be nice to log progress of the Cloud Build when running tfc.run.
