Changes from previous version:
* Service initialization is reduced to just creating the "/etc/dropbear"
directory.
* The initialize and host-key options are removed.
* The -R flag has been added to dropbear.
Example service file:
```scheme
(use-modules (gnu))
(use-service-modules base networking ssh)
(operating-system
(host-name "test")
(timezone "Europe/Zurich")
(locale "en_US.UTF-8")
(bootloader (grub-configuration (device "/dev/vda")))
(file-systems (cons
(file-system
(device "/dev/vda1")
(mount-point "/")
(type "ext4"))
%base-file-systems))
(users (cons
(user-account
(name "test")
(group "users")
(supplementary-groups '("wheel"))
(home-directory "/home/test")
(password "sa5JEXtYx/rm6")) ;; password pass
%base-user-accounts))
(packages %base-packages)
(services (cons*
(dhcp-client-service)
(dropbear-service
#:port-number 22
#:allow-empty-passwords? #t
#:root-login? #t
#:syslog-output? #t
#:pid-file "/var/run/dropbear.pid"
#:password-authentication? #t)
(rngd-service)
%base-services)))
```
Additional information:
This patch is needed, just adding -net user,hostfwd=tcp::10022-:22 at the end
didn't work for me.

You can use this command to connect to dropbear:
ssh -o UserKnownHostsFile=/dev/null -o StrictHostKeyChecking=no test@localhost
-p 10022
I'm currently having an issue with all guix operations after commit 4ee96a7 but
I
tested it with previous commits. I'm assuming that the problem is related to
nixos
and that it shouldn't affect people using guixsd.

gnu: lsh: Move to (gnu packages ssh)
services: Add 'dropbear-service'.
