* Use gsutil to configure the logs bucket's lifecycle,
which is not in the gc_storage module yet.
(See https://cloud.google.com/storage/docs/gsutil_install).
* Generate uniq bucket names extended with the build's OS type info as well.
* Ignore boto related errors for the gc_storage module.
* Use no_log when needed to supress noise/secrets in output
