secrets: make configuration more robust
- Fail at evaluation when secrets setup is not configured.
  Previously, bitcoind failed at runtime due to the missing secrets target.

- Fail at evaluation when conflicting secrets setup methods are used.
  This happens when `secretsSetupMethod` has more than one definition.

secrets: don't stop services when the secrets target stops
With krops or nixops the secrets target is always restarted during
the deployment process.
This previously caused unnecessary restarts of all nix-bitcoin services.

secrets: add option 'generateSecrets'
Move this feature from a module preset to a regular option, so that it's
easily discoverable and accessible.

Simplify the implementation of `generateSecrets` by adding it to the
existing `setup-secrets` service script.

Also rename option setup-secrets -> setupSecrets.

onion-addresses: mirror nix-bitcoin.onionAddresses.access behavior
This commit fixes an issue with LND, in which if both
nix-bitcoin.onionServices.lnd.public &
services.lnd.restOnionService.enable were enabled, one would try to
create a file named `lnd` and the other would try to create a directory
named `lnd` with a file named `lnd-rest` inside it. This would obiously
cause an error and fail the LND service.

treewide: remove unit descriptions
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...
```

onionServices: use actual user name of services
Previously, onionAddresses definitions in onionServices were of the form
onionAddresses.access.<service> = [<service>];

This caused failures for configurations where a service user name was
overridden or for bitcoind whose default user is 'bitcoin' instead of 'bitcoind'.

Now set the equivalent of:
onionAddresses.access.<actualServiceUser> = [<service>];

Implement this via a new option `onionAddresses.services` to make things more
readable and to work around an infinite recursion error in onionServices.

fix 'hardened' profile for NixOS 20.09
The 'scudo' memory allocator set by the 'hardened' profile breaks some
services on 20.09.
The fix for NixOS unstable (https://github.com/NixOS/nixpkgs/pull/104052)
is ineffective on 20.09.

As a workaround, add a custom 'hardened' preset that uses the default allocator.
