Robert Schütz 15b859cefe nixos/nextcloud: set X-Robots-Tag to "noindex, nofollow"
Upstream did so in https://github.com/nextcloud/server/pull/36689 and
Nextcloud now complains that

    The "X-Robots-Tag" HTTP header is not set to "noindex, nofollow".
    This is a potential security or privacy risk, as it is recommended
    to adjust this setting accordingly.

The nextcloud module supports `nginx` as reverse-proxy by default and doesn't
support other reverse-proxies officially.
However it's possible to use an alternative reverse-proxy by
* disabling nginx
* setting `listen.owner` & `listen.group` in the phpfpm-pool to a different value
Further details about this can be found in the `Nextcloud`-section of the NixOS-manual
(which can be opened e.g. by running `nixos-help`).

This option enables using the OpenSSL PHP extension linked against OpenSSL 1.1
rather than latest OpenSSL ( 3), this is not recommended unless you need
it for server-side encryption (SSE). SSE uses the legacy RC4 cipher which is
considered broken for several years now. See also [RFC7465](https://datatracker.ietf.org/doc/html/rfc7465).
This cipher has been disabled in OpenSSL 3 and requires
a specific legacy profile to re-enable it.
If you deploy Nextcloud using OpenSSL  3 for PHP and have
server-side encryption configured, you will not be able to access
your files anymore. Enabling this option can restore access to your files.
Upon testing we didn't encounter any data corruption when turning
this on and off again, but this cannot be guaranteed for
each Nextcloud installation.
It is `true` by default for systems with a [](#opt-system.stateVersion) below
`22.11` to make sure that existing installations won't break on update. On newer
NixOS systems you have to explicitly enable it on your own.
Please note that this only provides additional value when using
external storage such as S3 since it's not an end-to-end encryption.
If this is not the case,
it is advised to [disable server-side encryption](https://docs.nextcloud.com/server/latest/admin_manual/configuration_files/encryption_configuration.html#disabling-encryption) and set this to `false`.
In the future, Nextcloud may move to AES-256-GCM, by then,
this option will be removed.
