Use the following order of definitions for all services:
- assertions
- configuration of other services
- environment.systemPackages
- tmpfiles
- own service
- users
- secrets
Systemd's `Description` option is a misnomer (as confessed by `man systemd.unit`):
Its value is used by user-facing tools in place of the unit file name, so this option
could have been more aptly named `label` or `name`.
`Description` should only be set if the unit file name is not sufficient for naming a unit.
This is not the case for our services, except for `systemd.services.nb-netns-bridge`
whose description has been kept.
As an example how this affects users, weird journal lines like
```
nb-test systemd[1]: Starting Run clightningd...
```
are now replaced by
```
nb-test systemd[1]: Starting clightning.service...
```
This also enables the test scenario 'netnsRegtest' introduced in a
later commit by fixing the following bug:
For unknown reasons, when tor.active=true and tor is not running, lnd
fails with a tor connection error on netns-isolation, but runs fine
without netns-isolation.
- Adds bitcoind-host, and tor-socks options to allow using with
network namespaces.
- Adds listen, rpclisten, and restlisten option to specify host on which
to listen on for peer, rpc and rest connections respectively
- Adds announce-tor option and generates Tor Hidden Service with nix
instead of lnd to bring in line with clightning.
WARNING: Breaking changes for Tor Hidden Service. Manual migration
necessary.

Add ProtectSystem=strict, remove PermissionStartOnly.
Extract the section of postStart that needs secrets dir write
access into a separate script with full privileges.
Simplify preStart and fix dataDir quoting.
Remove PermissionsStartOnly for bitcoind and spark-wallet (it was never
needed there)
Give reason for PermissionsStartOnly in lightning-charge
Replace PermissionsStartOnly in clightning, electrs and liquid
This is NixOS' recommended way to setup service dirs
https://github.com/NixOS/nixpkgs/pull/56265. This commit hands off the
initial data directory creation to systemd.tmpfiles.rules. All other
preStart scripts are left intact to limit this changes' scope.
In conjuction with secure-node.nix, this sets sane
RestrictAddressFamilies unless lnd is enabled. Before, we were
constantly exposing unnecessary Address Families, not just when lnd is
enabled.
However, zmqpub* must always be enabled for lnd, even when used
outside of secure-node.nix, so we make this change in the lnd module.
