`tree` returns exit status 1 if there is any non-authorized view

[yu-iskw]

Motivation

We take advantage of dbt to transform BigQuery tables as well as manage authorized views with terraform. We would like to just check whether or not authorized view chains break up rather than grant permissions with the tool. So, we would like to run the check command on CI. To do that, it would be awesome for the tree command to return exit statu1 if there is any no-authorized view in the pass.

Hey @yu-iskw, that sounds like a useful and reasonable feature request. I'm no longer involved in this project, but @TWinsnes or @polleyg will happily take your request on board and prioritise accordingly.
