Sayam Samal a7772f86a2 docs: Update CZO links from stream to channel in docs and comments.
Updates all the https://chat.zulip.org/#narrow/stream/ links in the
docs and comments to use the new /channel/ path. All these links are
for documentation/reference purposes only and thus, can be bulk-updated.

This commit is a part of the effort to rename stream to channel.

Anders Kaseorg 75525f5b53 docs: Convert .html#fragment links to .md#fragment.
This uses the myst_heading_anchors option to automatically generate
header anchors and make Sphinx aware of them.  See
https://myst-parser.readthedocs.io/en/latest/syntax/optional.html#auto-generated-header-anchors.

Note: to be compatible with GitHub, MyST-Parser uses a slightly
different convention for .md fragment links than .html fragment links
when punctuation is involved.  This does not affect the generated
fragment links in the HTML output.

Fixes #13264.

Alex Vandiver e94b6afb00 nagios: Remove broken check_email_deliverer_* checks and related code.
These checks suffer from a couple notable problems:
 - They are only enabled on staging hosts -- where they should never
   be run.  Since ef6d0ec5ca, these supervisor processes are only
   run on one host, and never on the staging host.
 - They run as the `nagios` user, which does not have appropriate
   permissions, and thus the checks always fail.  Specifically,
   `nagios` does not have permissions to run `supervisorctl`, since
   the socket is owned by the `zulip` user, and mode 0700; and the
   `nagios` user does not have permission to access Zulip secrets to
   run `./manage.py print_email_delivery_backlog`.

Rather than rewrite these checks to run on a cron as zulip, and check
those file contents as the nagios user, drop these checks -- they can
be rewritten at a later point, or replaced with Prometheus alerting,
and currently serve only to cause always-failing Nagios checks, which
normalizes alert failures.

Leave the files installed if they currently exist, rather than
cluttering puppet with `ensure => absent`; they do no harm if they are
left installed.

Alex Vandiver 476524c0c1 scripts: Add a script to stop the server.
Using `supervisorctl stop all` to stop the server is not terribly
discoverable, and may stop services which are not part of Zulip
proper.

Add an explicit tool which only stops the relevant services.  It also
more carefully controls the order in which services are stopped to
minimize lost requests, and maximally quiesce the server.

Locations which may be stopping _older_ versions of Zulip (without
this script) are left with using `supervisorctl stop all`.

Tim Abbott d70e799466 bots: Remove FEEDBACK_BOT implementation.
This legacy cross-realm bot hasn't been used in several years, as far
as I know.  If we wanted to re-introduce it, I'd want to implement it
as an embedded bot using those common APIs, rather than the totally
custom hacky code used for it that involves unnecessary queue workers
and similar details.

Anders Kaseorg ea6934c26d dependencies: Remove WebSockets system for sending messages.
Zulip has had a small use of WebSockets (specifically, for the code
path of sending messages, via the webapp only) since ~2013.  We
originally added this use of WebSockets in the hope that the latency
benefits of doing so would allow us to avoid implementing a markdown
local echo; they were not.  Further, HTTP/2 may have eliminated the
latency difference we hoped to exploit by using WebSockets in any
case.

While we’d originally imagined using WebSockets for other endpoints,
there was never a good justification for moving more components to the
WebSockets system.

This WebSockets code path had a lot of downsides/complexity,
including:

* The messy hack involving constructing an emulated request object to
  hook into doing Django requests.
* The `message_senders` queue processor system, which increases RAM
  needs and must be provisioned independently from the rest of the
  server).
* A duplicate check_send_receive_time Nagios test specific to
  WebSockets.
* The requirement for users to have their firewalls/NATs allow
  WebSocket connections, and a setting to disable them for networks
  where WebSockets don’t work.
* Dependencies on the SockJS family of libraries, which has at times
  been poorly maintained, and periodically throws random JavaScript
  exceptions in our production environments without a deep enough
  traceback to effectively investigate.
* A total of about 1600 lines of our code related to the feature.
* Increased load on the Tornado system, especially around a Zulip
  server restart, and especially for large installations like
  zulipchat.com, resulting in extra delay before messages can be sent
  again.

As detailed in
https://github.com/zulip/zulip/pull/12862#issuecomment-536152397, it
appears that removing WebSockets moderately increases the time it
takes for the `send_message` API query to return from the server, but
does not significantly change the time between when a message is sent
and when it is received by clients.  We don’t understand the reason
for that change (suggesting the possibility of a measurement error),
and even if it is a real change, we consider that potential small
latency regression to be acceptable.

If we later want WebSockets, we’ll likely want to just use Django
Channels.

This also rewrites the text to better explain what's happening.  It's

This block of text was misplaced when we split the long

folks who are looking into error emails Zulip is sending.

* Replaces "API and your Zulip URL" with a link to REST API docs.  This

* Removes maintain-secure-upgrade from the TOC but the file remains to

David Rosa bdbc384de5 docs: Reduce the number of apparently broken links on github.
- Updated 260+ links from ".html" to ".md" to reduce the number of issues
reported about hyperlinks not working when viewing docs on Github.
- Removed temporary workaround that suppressed all warnings reported
by sphinx build for every link ending in ".html".

Details:
The recent upgrade to recommonmark==0.5.0 supports auto-converting
".md" links to ".html" so that the resulting HTML output is correct.

Notice that links pointing to a heading i.e. "../filename.html#heading",
were not updated because recommonmark does not auto-convert them.
These links do not generate build warnings and do not cause any issues.
However, there are about ~100 such links that might still get misreported
as broken links.  This will be a follow-up issue.

Background:
docs: pip upgrade recommonmark and CommonMark #13013
docs: Allow .md links between doc pages #11719

Fixes #11087.

Samuel Searles-Bryant c87893feea docs: Update .html links to .md.
Sphinx/ReadTheDocs supports automatically translating links written as
to `.md` files to point to the corresponding `.html` files, so this
migration does not change the resulting HTML output in ReadTheDocs.
But it does fix apparent broken links on GitHub.

This doesn't prevent people from reading the documentation on GitHub
(so doesn't mitigate the fact that some rtd-specific syntax does not
render properly on GH), but it will prevent us from getting erroneous
issues reported about the hyperlinks not working.

Fixes: #11087.

David Rosa Tamsen 7072fa5b37 docs: Reorganize developer docs to improve navigation.
This commit helps reduce clutter on the navigation sidebar.
Creates new directories and moves relevant files into them.
Modifies index.rst, symlinks, and image paths accordingly.

This commit also enables expandable/collapsible navigation items,
renames files in docs/development and docs/production,
modifies /tools/test-documentation so that it overrides a theme setting,
Also updates links to other docs, file paths in the codebase that point
to developer documents, and files that should be excluded from lint tests.

Note that this commit does not update direct links to
zulip.readthedocs.io in the codebase; those will be resolved in an
upcoming follow-up commit (it'll be easier to verify all the links
once this is merged and ReadTheDocs is updated).

Fixes #5265.
