PostGIS upgrade tests shoudl fail and exit after first failure

[robe]

Dronie tests all upgrade paths and when she runs into a failure she continues on, but flags the job as failed.

The issue is it's hard to tell where it failed unless you scroll thru the whole transcript.

Would be better if upgrade steps just fail and exit without continuing on. That would serve 2 purposes

1) Make it easier to see where the error is 2) Less resource intensive, no point continuing when we have a crisis on our hands.

In 17363:

Add -s switch to check_all_upgrades to stop on first failure

Also have Dronie use that switch.
