clightning: add announce-tor
From the clightning manpage:

autolisten=BOOL By default, we bind (and maybe announce) on IPv4 and
IPv6 interfaces if no addr, bind-addr or  announce-addr options  are
specified. Setting this to false disables that.

We already set bind-addr by default, so autolisten had no effect.
Therefore, this commit replaces autolisten with the more granular
announce-addr option.

For now we are Tor-only, so we only need to announce our hidden service
to accept incoming connections. In the future, we can add clearnet
connectivity with `addr` and route connections into our netns with NAT.

netns-isolation: netns architecture
- Adds network namespace instantiation and routing architecture.
- netns-isolation disabled by default. Can be enabled with
  configuration.nix FIXME.
- Uses mkMerge to toggle certain options for non netns and netns
  systems.
- Adds security wrapper for netns-exec which allows operator to exec
  with cap_sys_admin
- User can select the 169.254.N.0/24 addressblock netns's are created in.
- nix-bitcoin-services IpAddressAllow is amended with link-local
  addresses

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.

lnd: only enable bitcoind zmqpub if lnd.enable
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.

so don't add nodeinfo and webindex to modules.nix because they will fail on standalone use.

clightning: update to v0.8.0
To continue using inotify would be too complicated because we would also need to
monitor the creation of the 'bitcoin' subdirectory.

Pull request description:

  The nix-bitcoin modules consist of three fundamental components:
  1. a set of bitcoin-related modules for general use.
  2. an opinionated configuration of these modules (`nix-bitcoin.nix`), to be deployed on a
     dedicated machine.
  3. machinery for nixops deployment.

  This PR removes dependencies that reach from top to bottom in the list.
  This means that 1. is now usable on its own and that 2. can be used without 3.

  Besides improving nix-bitcoin's general usefulness, this
  - simplifies testing. This PR includes a Travis-enabled modules test using the NixOS testing framework.
  - paves the way for krops deployment.
  - unlocks direct deployment in NixOS containers which allows for super fast experimentation.

  ### Details
  Here are the unnecessary inter-component dependencies and how they're resolved by the commits. I'm using the numbering from the list above.

  - `1. -> 3.` The modules (1.) use the nixops-specific (3.) `keys` group.
    Resolved by `add nix-bitcoin-secrets.target`.

  - `1. -> 3.` 1. requires nixops-specific key services.
    Resolved by `add nix-bitcoin-secrets.target`.

  - `1. -> 2.` bitcoind needs the bitcoinrpc group which is defined in `nix-bitcoin.nix` (2.).
    Resolved by `move bitcoinrpc group definition to bitcoind`.

  Further obstacles for standalone usage of 1.:

  - We can't easily import 1. as a standalone module set.
    Resolved by `add modules.nix`.

  - Users of 1. shouldn't be forced to import nix-bitcoin's packages as top-level items in the pkgs namespace.
    Resolved by `add nix-bitcoin pkgs namespace`.

  ### Non-nixops deployments
  Commit `add setup-secrets.service` simplifies non-nixops deployment methods like containers, NixOS VMs or krops.

  Secrets can now deployed as follows:
  1. create local secrets.
  2. transfer secrets to machine.
  3. on the machine, `setup-secrets.service` creates extra secrets from `secrets.nix` and sets owner and
     permissions for all secrets.

  As krops integrates step 2. we now have all ingredients for automatic krops deployment.

  The service is complicated by the creation of secrets like `bitcoin-rpcpassword` that are composed of attrs from `secrets.nix` instead of being simply backed by a file like `lnd_key`. We could simplify this by creating all secret files locally.

  Running nix-bitcoin in NixOS containers gives you faster rebuild cycles when developing. [Here's](https://gist.github.com/5db4fa7dd3f1137920b58e39647116f6) an example.

  ### Test
  The last commits starting with `clightning: add cli option` are testing-related and mostly fix non-critical bugs that were exposed by the test.

  All `STABLE=1` builds from the Travis build matrix are implicit in the modules test.
  Should we remove these individual builds?

  Regarding commit `travis: cache all build outputs with cachix`:
  To replace my cache with a cache that's owned by you (maybe named `nix-bitcoin-ci`), run
  ```
  nix-shell -p travis --run 'travis encrypt CACHIX_SIGNING_KEY=... -r fort-nix/nix-bitcoin'
  ```
  where `...` is the value of `secretKey` in `~/.config/cachix/cachix.dhall`. Let me know the travis secret and I'll fixup the commit.

  ### Docs
  If you like the proposed changes, I'll add another PR with updates to the docs regarding the project layout, non-nixops deployment, and how to use nix-bitcoin within a larger NixOS config.

make secrets dir location configurable
Users of the nix-bitcoin modules shouldn't be forced to add an extra
dir under root.
The secrets location is unchanged for the default node config.

simplify secrets file format
Each secret file to be deployed is now backed by one local file.
This simplifies 'setup-secrets' and the secret definitions.
Also, with the old format it was not possible to add new secrets
to secrets.nix in a simple way.

Old secrets are automatically converted to the new format when running
nix-shell.

Using the new option 'nix-bitcoin.secrets', secrets are now directly
defined by the services that use them.
