- Adds lnd to netns-isolation.services
- Specifies listen option (defaults to localhost) as target of
hiddenService.
- Amends hardcoded lnd ip to lnd-cert
WARNING: Breaking changes for lnd cert. lnd-key and lnd-cert will have
to be deleted and redeployed.
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.
