Tim Abbott 957c16aa77 nagios: Tweak prod load monitoring parameters.
Ultimately this monitoring isn't that helpful, but we're mainly
interested in when it spikes to very high numbers.

Alex Vandiver 173d2dec3d puppet: Check in defensive restart-camo cron job.

Alex Vandiver e30b524896 iptables: Limit smokescreen port 4750, add camo port.
Limit incoming connections to port 4750 to only the smokescreen host,
and also allow access to the Camo server on that host, on port 9292.

Alex Vandiver 559cdf7317 puppet: Set APT::Periodic::Unattended-Upgrade in apt config.
This is required for unattended upgrades to actually run regularly.
In some distributions, it may be found in 20auto-upgrades, but placing
it here makes it more discoverable.

Tim Abbott fd8504e06b munin: Update to use NAGIOS_BOT_HOST.
We haven't actively used this plugin in years, and so it was never
converted from the 2014-era monitoring to detect the hostname.

This seems worth fixing since we may want to migrate this logic to a
more modern monitoring system, and it's helpful to have it correct.

Alex Vandiver c2526844e9 worker: Remove SignupWorker and friends.
ZULIP_FRIENDS_LIST_ID and MAILCHIMP_API_KEY are not currently used in
production.

This removes the unused 'signups' queue and worker.

Alex Vandiver 90ca06d873 puppet: Allow unattended upgrades of -updates in addition to -security.
This ensures that software will be fully up-to-date, not just with
security patches.

Tim Abbott 494a685827 puppet: Fix typo in name of missedmessage_emails consumer.
This has been present since this check was introduced in
45c9c3cc30.

Tim Abbott ab3cb2b3bf puppet: Fix internal redis puppet configuration.
The inherits rule is required for overriding existing configuration
files; while the `::profile` piece was missed in the recent ::profile
migration.

Alex Vandiver a155430eb5 docs: Document all zulip.conf settings.
This provides a single reference point for all zulip.conf settings;
these mostly link out to the more complete documentation about each
setting, elsewhere.

Fixes #12490.

Alex Vandiver 188af57296 puppet: Rename postgres_appdb to postgresql.
There is only one PostgreSQL database; the "appdb" is irrelevant.
Also use "postgresql," as it is the name of the software, whereas
"postgres" the name of the binary and colloquial name.  This is minor
cleanup, but enabled by the other renames in the previous commit.

Alex Vandiver c2185a81d6 puppet: Move top-level zulip deployments into "profile" directory.
This moves the puppet configuration closer to the "roles and profiles
method"[1] which is suggested for organizing puppet classes.  Notably,
here it makes clear which classes are meant to be able to stand alone
as deployments.

Shims are left behind at the previous names, for compatibility with
existing `zulip.conf` files when upgrading.

Alex Vandiver 27cfb14d92 puppet: Only include zulip::base for top-level deploys.
This also removes direct includes of `zulip::common`, making
`zulip::base` gatekeep the inclusion of it.  This helps enforce that
any top-level deploy only needs include a single class, and that any
configuration which is not meant to be deployed by itself will not
apply, due to lack of `zulip::common` include.

The following commit will better differentiate these top-level deploys
by moving them into a subdirectory.

Alex Vandiver c296b5d819 puppet: Allow unattended-upgrades for all but servers.
Restarting servers is what can cause service interruptions, and
increase risk.  Add all of the servers that we use to the list of
ignored packages, and uncomment the default allowed-origins in order
to enable unattended upgrades.

Alex Vandiver a7d1fd9ffb puppet: Remove non-working apt::source.
d2aa81858c replaced the `apt::source` to set up debathena with
`Exec['setup-apt-repo-debathena']`, but mistakenly left the
`apt::source` in place in `zmirror` (but not `zmirror_personals`).
The `apt::source` resource type was later removed in c9d54f7854,
making the manifest to apply on `zmirror`.

Remove the broken and unnecessary `apt::source` resource.

will be removed in a future release.

Alex Vandiver 0ea20bd7d8 puppet: Move postgres_version into postgres_common.
This property is not related to the base zulip install; move it to
zulip::postgres_common, which is already used as a namespace for
various postgres variables.

Alex Vandiver 50e9e2ed20 puppet: Make zulip::base include zulip::apt_repository.
There was likely more dependency complexity prior to 97766102df, but
there is now no reason to require that consumers explicitly include
zulip::apt_repository.

Alex Vandiver 7a1132d605 puppet: Switch golang and smokescreen to use /srv.
/srv and /opt have very similar usages; but we should be internally
consistent.

Move these two (the only usages of /opt) to match the rest in /srv.

Alex Vandiver fffea9612b puppet: Add an outgoing HTTP/HTTPS proxy server.
Use https://github.com/stripe/smokescreen to provide a server for an
outgoing proxy, run under supervisor.  This will allow centralized
blocking of internal metadata IPs, localhost, and so forth, as well as
providing default request timeouts (10s by default).

This allows it to be pulled in for deploys like czo, which don't use

Tim Abbott 7c2c82b190 nginx: Update nginx configuration for fhir/hl7 organization.
We should eventually add templating for the set of hosts here, but
it's worth merging this change to remove the deleted hostname and

Alex Vandiver c8df9a150e puppet: Drop all log2zulip configuration.
Disabled on webservers in 047817b6b0, it has since lingered in
configuration, as well as running (to no effect) every minute on the
loadbalancer.

Remove the vestiges of its configuration.

Alex Vandiver b431b1b021 puppet: Remove misleading motd.
This banner shows on lb1, advertising itself as lb0.  There is no
compelling reason for a custom motd, especially one which needs to
be reconfigured for each host.

Alex Vandiver 45c9c3cc30 queue: Monitor user_activity queue, now that it has a consumer.
Since this was using repead individual get() calls previously, it
could not be monitored for having a consumer.  Add it in, by marking
it of queue type "consumer" (the default), and adding Nagios lines for
it.

Also adjust missedmessage_emails to be monitored; it stopped using
LoopQueueProcessingWorker in 5cec566cb9, but was never added back
into the set of monitored consumers.
