This option allows users to specify a local UNIX control socket to
"remote control" the daemon. System users, that should be permitted to
access the daemon, must be in the `unbound` group in order to access the
socket. When a socket path is configured we are also creating the
required group.
Currently this only supports the UNIX socket mode while unbound actually
supports more advanced types. Users are still able to configure more
complex scenarios via the `extraConfig` attribute.
When this option is set to `null` (the default) it doesn't affect the
system configuration at all. The unbound defaults for control sockets
apply and no additional groups are created.
The test relied on moving `initrd` secrets from the store into the
`initrd` which was fine here as it's only an integration test and not a
production environment.
However, this broke in 20.09 when support for this was dropped[1]. To make
sure that the snakeoil key used as hostkey for `sshd` here actually gets
copied into the VM, I added a small script for this that takes care of
this process while building the initial ramdisk.

This test allows to ensure the systemd-journal-gatewayd service is
responding correcly when the NixOS option `enableHttpGateway` is set.
The test has not been added into the main systemd test because a
graphical stack is not required (and rebuilding the graphical stack on
systemd change is huge).
Upstream has apparently changed the configuration format and is now
throwing an error when the `encrypt_sse` option is set. According to the
current version of the documentation encryption moved to the
`sse_config` option that (is optional and) offers all the features we do
not use or care about for this test.
