nanopos: add netns - Adds nanopos to netns-isolation.services - Adds cfg.enforceTor and extraArgs to bring nanopos in line with other services - Adds charged-url option to allow using nanopos with network namespaces. - Modularizes nginx so webindex can be used without nanopos. - Adds host option (defaults to localhost) as target of hidden service - Removes unnecessary after

clightning: add cli option An executable is more robust to use than shell aliases. This is also a preparation for commit 'add module test' because the NixOS testing framework makes interactive aliases hard to use: It unsets 'PS1' which is used by programs/bash/bash.nix to detect interactive shells.
