* Silence curl command
* Update more files with -sS (adding S to show errors)
* Over-agressive on the -S and causing some tests to fail.
* Remove more curl -S flags
Reverted the actual mirror test script, because mirror test seems to have some subtle failure when running with what seems to be the exact same commands via snips. Will investigate further in followup PR. Merging this one to get the generator changes.
