archweb: Put most services after network-online.target

See merge request !486

We noticed readlinks and reporead on gemini failing to connect to the
archweb database immediately after rebooting. To fix this, place them
after network-online.target. Do the same for all but one of the other
service units even though they run on timers 10-15 minutes after boot
for completeness and correctness.

The JournalHandler doesn't support flushing, anyway.

Add simple playbook task for upgrading servers

We want to treat our servers as cattle; hopefully when this is fleshed
out a bit more, it can accomplish the job without too many casualties.

This is done to avoid killing db-update and related processes.

It has been applied upstream[1] and released with smartmontools 7.2[2].

This reverts commit b4c97002.

Ref: service-agreements!16

We used to set query_cache_type to 0 in the default settings but we were
also setting query_cache_size to a non-zero/non-default value, which was
in turn re-enabling the query cache. Update the configuration to reflect
the actual cache state and make sure query_cache_size is set to zero for
the "query_cache_type = 0" case.

Now that the setting controls the real state of the query cache, disable
it for bbs.archlinux.org; its hit rate is small compared to insert rate.

Default query_cache_type to 0 and innodb_file_per_table to true.
