Cut Azure costs: uptime check off, delete old registry images after deploys - #64

The availability test was most of the Azure bill: 864 billed checks a day from three regions, and frequent enough that the apps never scaled to zero. The live test and the "Site is down" alert were changed to one region (Chicago) every 15 minutes on Oct 29; this updates the guide to match and explains the trade-off.

- scripts/prune-images.sh keeps the newest 10 images of each app, plus whatever each app is running, and deletes the rest. It deletes whole manifests by digest (never by tag, which could take a kept tag with it), keeps the inner manifests of kept images, and stops without deleting if any lookup fails. DRY_RUN=1 shows what it would delete. Tested against a simulated registry with nested, shared and rolled-back images. - The deploy runs it after the live site check; a failure there doesn't fail the deploy. - docs/monitoring.md: the availability test is now turned off to save money, with the command to turn it back on.

Cuts Azure costs. Changes the deploy and the docs; no app code.
Uptime check off. The availability test is turned off in Azure to save money.
docs/monitoring.mdexplains why and gives the one command to turn it back on. When it is on, it now checks from one region every 15 minutes, not three regions every 5.Old registry images deleted after each deploy.
scripts/prune-images.shkeeps the newest 10 images of each app, plus whatever each app is running, and deletes the rest, so the registry stays within the 10 GB its Basic plan includes. The deploy runs it after the live-site check passes, and a failure there does not fail the deploy.Safety:
DRY_RUN=1lists what it would delete without deleting.Before merging: the deploy identity needs the AcrDelete role on the registry, and a dry run should be checked first. See the conversation for the commands.
