edebf7619b puppet: Add PAM common_session disabling systemd-login. 
This fixes a weird problem with systemd where logging into a server
via ssh frequently has a 15s+ lag.

3e01ed1f73 nagios: Increase NTP max_check_attempts. 
NTP often suffers from brief interruptions of service that lead to
spurious Nagios alerts; it makes sense to suppress these.

e4420b08d2 zulip_ops: Disable unattended upgrades of security packages. 
Since Zulip does not handle e.g. postgres server restarts gracefully,
it's best for a system administrator to manually trigger security
updates.

bd9176d1d9 nagios: Remove some default files. 
Nagios ships with a bunch of default configuration files that one
needs to delete in order to configure it.

7083899e77 zulip_ops: Add postgres config for enabling Nagios. 
The old zulip_ops Nagios configuration depended on Nagios having the
ability to login as the zulip user (with essentially full write
access); this configuration is helpful for limiting nagios to special
"nagios" user with more limited credentials.

165b4d3126 nagios: Fix check_send_receive_time threshholds. 
Previously, the CRITICAL state would never fire (because x > 6 =>
x > 3).  Additionally, 6s is not so unusually high as to deserve being
immediately pageable.

0d8c18a6dd nagios-plugins: Add websocket checking to nagios message sending test. 
- Add websocket client to create connection with SockJS websocket server.
  It contains callback method to launch after connection setup.
- Add '--websocket' parameter to 'check_send_receive_time' script to
  check websocket connection.
- Add testing  websocket connection to production installation checking.
- Add cronjob to launch websocket connection nagios test.

This makes it possible for Zulip Nagios monitoring to check for
problems impacting the websockets sending code path, which is what all
web users use.

c93f1d4eda Add oembed/Open Graph/Meta tags data retrieval from inline links. 
This change adds support for displaying inline open graph previews for
links posted into Zulip.

It is designed to interact correctly with message editing.

This adds the new settings.INLINE_URL_EMBED_PREVIEW setting to control
whether this feature is enabled.

By default, this setting is currently disabled, so that we can burn it
in for a bit before it impacts users more broadly.

Eventually, we may want to make this manageable via a (set of?)
per-realm settings.  E.g. I can imagine a realm wanting to be able to
enable/disable it for certain URLs.
