arv-run-pipeline-instance sends error message to logs table when job submission
fails.  Pipeline instance view in workbench now shows messages for the pipeline
instance (in addition to the jobs) and shows messages when the pipeline is
failed (not only when it is running.)
Update package version dependencies on arvados-cli to use commit:7bd2ee2
Google API client jsonifies the body, so we don't have to.
Merge branch '3123-pipeline-report-job-submit-errors' closes #3123
