Add controller.max_send_buffer_size in MiB, default 64 and 0 for no
limit. Close with 1013 instead of 1008 on overflow: clients treat 1008
as fatal, so a host would shut down and the web UI would log out. With
1013 the client resumes, the controller answers with invalidate since
the session has ended, and the client registers a new session.

Lowering the limit at runtime would leave connections holding more
filters than allowed, so read it once when the controller starts.
Move the limit tests into the subscribe and replace groups.

A subscriber could keep sending subscribe requests with new filters and
the controller would add every one of them to the subscriber's filter
set without bound, growing memory until it ran out.
Add controller.max_subscription_filters (default 10000) and reject
subscribe and replace requests that would leave a subscriber holding
more filters than that for one event.

Ctl ended up calling its main class for "Control" for historical
reasons, along with its config file and plugin entrypoint.
The plugin entrypoint was renamed to ctl in 808eda0513. This
finishes that renaming by also renaming the main class, default config
file, config-control command, and main entrypoint.
The config-control command is renamed to config to be consistent with
the host and controller's config commands.
The term "control" is still kept in the config and message locations as
a common specifier for both ctl and web_ui.
configuration.md was missing most options added over the last few years. Add the controller, host and instance options that weren't listed, mark the internal ones, note the validation rule under each field that has one, and fix entries that had gone stale: the tls defaults, the proxy_stream_timeout name, game port assignment from host.factorio_port_range, the three sync list modes, and the player_online_autosave_slots heading.
Plugin options live in the plugin READMEs, so add the missing ones for inventory_sync, player_auth and subspace_storage there. config-system.md gets the field definition properties it didn't list yet.

Add option in the controller config to set where static assets are
loaded from in order to support deployments where the static assets are
server via a CDN while the API is directly accessed.
This is useful because some CDNs put low limits on how large requests
bodies can be, which causes issues with uploading large mods and saves.
The migration from phin to fetch in #755 was hampred by the lack of an
option to set the CA when using fetch. This meant places that used phin
to talk to the controller with the tlsCa option could not be migrated to
use fetch.
Remove the tlsCa option to unblock this dependency. The replacement for
this option is to set the NODE_EXTRA_CA_CERTS environment variable to a
path to the certificate file instead, which works with fetch.
The role of a slave as a host for Factorio servers is not well reflected
in its name and has caused confusion among users. Rename slave to host
to better reflect its role as a host of Factorio servers.
The role of the master server as the party controlling every part of the
cluster is not well reflected in its name and has caused confusion among
users on several occasions. Rename master to controller to better
reflects its role.
Add /api/upload-save endpoint that streams the data via the slave
assigned to the target instance to the instance saves directory, along
with a ctl command and web interface button to do the upload.
Simplify the the way markdown files are formatted to make them easier to
author without editors that do auto line breaking, and make the diffs
from them simpler to read.
Rename the config and status indicating whether to load a plugin or not
from "Enabled" to "Load Plugin". The latter better describes what it
does, and unlike the former doesn't imply plugins can be enabled or
disabled on the fly.
Add settings of interest to server administrators that appear in
server-settings.json to the factorio.settings config. This makes it
easier to see which settings can be set there.
The automatic creation of a self-signed certificate while nice presents
several problems. To make connections not reject the self-signed
certificate the validation of TLS certificates are wholesale disabled,
decreasing the security even when properly set up and trusted
certificates are used.
To make the created self-signed certificate pass validation it is
necessary for it to list the host names it's valid for and to copy it to
each machine that intends to connect to the server. These two steps
complicate automating the process in a reliable way and will likely lead
to confused users seeking to disable TLS certificate validation as the
easy way out to problems.
For these reasons, remove the automating creation of a broke self-signed
certificate, fix validation of certificates and document how to set up
TLS properly. This makes HTTPS recommended when accessing over the
internet, but still something which must be explicitly configured.
When reducing the collection interval in Prometheus it may be necessary
to to reduce the metrics gathering timeout to ensure it's less than the
interval. Add config options to adjust the timeouts used for metrics
gathering so that these can be set accordingly.
Add option to set the the maximum amount of commands transmitted in
parallel to the game. Increasing this value allows a greater rate of
commands to be executed.
Use 45 seconds as the default heartbeat interval instead of 60. Using
60 causes connections to drop when proxied through Nginx as the default
timeout there is also 60 seconds.
