Integrate Pangolin Newt Blueprint

[michimussato]

Include a newt service "wrapper" to Landscapes so that Features (if desired) can be launched with a connection to Pangolin.

Something like:

include:
    # ComposeScope-default
  - project_directory: .landscapes/<LANDSCAPE_ID>/...
    path:
      - ./.../docker-compose.yml
    env_file:
      - ./.../.env

services:
  newt:
    image: fosrl/newt
    container_name: newt
    restart: unless-stopped
    environment:
      - PANGOLIN_ENDPOINT=${PANGOLIN_ENDPOINT}
      - NEWT_ID=${NEWT_D}
      - NEWT_SECRET=${NEWT_SECRET}
      - ACCEPT_CLIENTS=${ACCEPT_CLIENTS}
