1656: Add ability to set no WEBROOT_REDIRECT to Nginx r=mergify[bot] a=DavidFair

## What type of PR?

Enhancement / Documentation

## What does this PR do?

From commit:

---

Adds a 'none' env option to WEBROOT_REDIRECT so that no `location /`
configuration is written to nginx.conf.

This is useful for setting up Mailu and Mailman where we override the
root to proxy to the mailing list server instead. Without this change
the nginx container will not start, or for 1.7 users can set their
WEBMAIL_PATH to / with no webmail to get the same results.

This fix means that future users don't have to choose between webmail
and a root override and makes the configuration intention clear.

---

I've also added bullet points to break up a long flowing sentence in `configuration.rst` - it should be a bit easier to read now

1618: add OCSP stapling to nginx.conf r=mergify[bot] a=lub

It's not added in tls.conf, because apparently the mail ssl module
doesnt' support OCSP stapling.

https://nginx.org/en/docs/http/ngx_http_ssl_module.html#ssl_stapling
^ exists

https://nginx.org/en/docs/mail/ngx_mail_ssl_module.html#ssl_stapling
^ missing

When the configured certificate doesn't have OCSP information, it'll
just log a warning during startup.

## What type of PR?

enhancement

## What does this PR do?

It enables OCSP stapling for the http server. OCSP stapling reduces roundtrips for the client and reduces load on OCSP responders.

Dario Ernst b6716f0d74 Remove "CHUNKING" capability from nginx-smtp
With `CHUNKING`set as a capability, nginx advertises this capability to
clients at a stage where the SMTP dialog does not seem to be forwarded
to the proxy-target (postfix) yet. Nginx' SMTP parser itself does not
support the `BDAT` command issued as part of a chunke-d dialog. This makes
Nginx respond with a `250 2.0.0 OK` and close the connection, after the
mail-data got sent by the client — without forwarding this to the
proxy-target.

With this, users mail can be lost.

Furthermore, when a user uses a sieve filter to forward mail, dovecot
sometimes chunks the forwarded mail when sending it through `front`.
These forwards then fail.

Removing `CHUNKING` from the capabilities fixes this behavior.

lub 0cb0a26d95 relax TLS settings on port 25
Because basically every MTA out there uses opportunistic TLS _in
the best case_, it's actually counter productive to use such strict
settings.

The alternative to a handshake error is often an unencrypted submission,
which is basically the opposite of what strict ssl_protocols and
ssl_ciphers tries to achieve.

Even big and established providers like Amazon SES are incompatible with the current
settings.

This reverts commit 2ddf46ad2b.

1181: Update to address issue #1178 (HTTP headers) r=muhlemmer a=bladeswords

This change should remove the duplicate `x-xss-protection` header and also the `x-powered-by` header.  Hopefully a pull request to main is appropriate, but may be worth back porting to 1.7.

Tested config by modifying live 1.7 nginx config and reloading.  Has had the desired outcome of removing the headers.

```/etc/nginx # nginx -t -c /etc/nginx/nginx.conf 
nginx: the configuration file /etc/nginx/nginx.conf syntax is ok
nginx: configuration file /etc/nginx/nginx.conf test is successful
/etc/nginx # nginx -s reload
```

These steps were based on:
