Instead of forking this repo, it is now recommended that users simply import the
nix-bitcoin module. This commit adds an example directory that contains the
network/ examples and a shell.nix for deployment with nixops.

Electrs allows defining settings multiple times via cmdline args, but
not via config files.
So 'extraArgs' is the only way to implement overridable settings,
'extraOptions' wouldn't work.
Use buildRustPackage instead of buildRustCrate (via crate2nix).
buildRustPackage builds the whole executable and its libraries in a
single `cargo build` process.
With the create2nix approach each library is built in a separate derivation,
directly using rustc instead of the cargo wrapper.
Benefits of buildRustPackage:
- Much simpler to maintain
- Package derivation evaluates much faster
Benefits of crate2nix:
- Build can be distributed over multiple build hosts
- Better sharing of common dependencies between different builds
- More fine-grained rebuilding on build failures
In nixpkgs buildRustPackage is used for almost all Rust pkgs, it's
also a better fit for our use case.

ProtectSystem=full disables writing to /etc which is the default
secrets location.
Besides that, hardening is pointless for {generate,setup}-secrets which
don't read external input and are fully under our control.

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.

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.
