Ensure daily apache2 graceful restart is splayed - LP:1918211 We ship out a random sleep script to cron.daily to ensure that graceful restarts from logrotation is spread out across the various units.

330	Add 'Accept-Encoding' in nrpe and health checks Add 'Accept-Encoding' in nrpe and health checks Upstream archives use mod_deflate which sets 'Vary: Accept-Encoding' on responses, so check_http should set that header. This also reduces the logging spam from squid: \| 2021/03/10 00:15:00 kid1\| varyEvaluateMatch: Oops. Not a Vary match on second attempt, 'http://archive.ubuntu.com/ubuntu/pool/' 'accept-encoding="*"' \| 2021/03/10 00:15:00 kid1\| clientProcessHit: Vary object loop! We also hope to reduce squid memory usage (mem_node) as discovered by tcuthbert.

327	Make health-check script/endpoint more resilient Make health-check script/endpoint more resilient u-r-c units are usually deployed in public clouds with the sync-host set to the main Ubuntu archive servers. We can't control the network connectivity/conditions so update health-check script to retry up to 3 times on failures.

326	Don't set health-check-disabled flag in apache.create_metada... Don't set health-check-disabled flag in apache.create_metadata_site() On non-leader units, metadata sync calls service.pause() which then calls this. This causes a brief period where the unit is disabled and not serving requests. It's useful for initial unit provisioning but not so on a fully functional unit where metadata points to an existing copy on disk. NOTE: The setting of health-check-disabled flag was introduced in r309 (MP:398100).

318	Add apache2 cgi script timeout Add apache2 cgi script timeout Otherwise, value of `Timeout` is used and that defaults to 60secs which is too long. We have two check points (metadata and pool) with a timeout in the health-check cgi script to 10secs for each so 20secs should be enough for both.
