Add Docker environment for development and testing of the web UI

Add --token parameter to easyinstall.sh Add --skip-token parameter to easyinstall.sh Install required apt packages explicitly (--no-install-recommends) Allow standalone RaSCSI and web UI installations to specify an auth token Add development mode to web UI (web/start.sh --dev-mode) Initial Docker-based development environment for Python and web UI Bump protobuf version Workaround for Flask development server and asyncio incompatibility Build Python protobuf interface on container launch, if it doesn’t exist Allow containers to be configured with environment variables, add support for token authentication Move web UI live editing setup out of main Docker Compose config Update dockerignore to exclude by default Update README Add OS_DISTRO, OS_VERSION and OS_ARCH build args Allow extracted files to be moved to target when crossing a filesystem boundary Reduce noise from watchmedo auto-restarts Update Docker tag structure to rascsi:{build}-{platform}-{variant} Prevent Docker Compose from attempting to pull images from Docker registry Add workaround for issue #821 Allow container processes to be stopped with Ctrl+C Update README, bind to ports 8080/8443 on the Docker host by default Update README to clarify audience and no board connectivity Add AIBOM and GAMERNIUM to --connect_type validation Update cfilesystem.patch following rebase

+# Docker Environment for Development and Testing
+
+⚠️ **Important:** The Docker environment is unable to connect to the RaSCSI board and is
+intended for development and testing purposes only. To setup RaSCSI on a Raspberry Pi
+refer to the [setup instructions](https://github.com/akuker/RASCSI/wiki/Setup-Instructions)
+on the wiki instead.
+
+## Introduction
+
+This documentation currently focuses on using Docker for developing and testing the web UI.
+
+Additions, amendments and contributions for additional workflows are most welcome.
+
+## Getting Started
+
+The easiest way to launch a new environment is to use Docker Compose.
+
+```
+cd docker
+docker compose up
+```
+
+Containers will be built and started for the RaSCSI server and the web UI.
+
+The web UI can be accessed at:
+
+* http://localhost:8080
+* https://localhost:8443
+
+To stop the containers, press *Ctrl + C*, or run `docker compose stop` 
+from another terminal.
+
+## Environment Variables
+
+The following environment variables are available when using Docker Compose:
+
+| Environment Variable | Default  |
+| -------------------- | -------- |
+| `OS_DISTRO`          | debian   |
+| `OS_VERSION`         | buster   |
+| `OS_ARCH`            | amd64    |
+| `WEB_HTTP_PORT`      | 8080     |
+| `WEB_HTTPS_PORT`     | 8443     |
+| `WEB_LOG_LEVEL`      | info     |
+| `RASCSI_HOST`        | rascsi   |
+| `RASCSI_PORT`        | 6868     |
+| `RASCSI_PASSWORD`    | *[None]* |
+| `RASCSI_LOG_LEVEL`   | debug    |
+
+**Examples:**
+
+Run Debian "bullseye":
+```
+OS_VERSION=bullseye docker compose up
+```
+
+Start the web UI with the log level set to debug:
+```
+WEB_LOG_LEVEL=debug docker compose up
+```
+
+## Volumes
+
+When using Docker Compose the following volumes will be mounted automatically:
+
+| Local Path              | Container Path           |
+| ----------------------- | ------------------------ |
+| docker/volumes/images/  | /home/pi/images/         |
+| docker/volumes/config/  | /home/pi/.config/rascsi/ |
+
+
+## How To
+
+### Rebuild Containers
+
+You should rebuild the container images after checking out a different version of
+RaSCSI or making changes which affect the environment at build time, e.g. 
+`easyinstall.sh`.
+
+```
+docker compose up --build
+```
+
+### Open a Shell on a Running Container
+
+Run the following command, replacing `[CONTAINER]` with `rascsi` or `rascsi_web`.
+
+```
+docker compose exec [CONTAINER] bash
+```
+
+### Setup Live Editing for the Web UI
+
+Use a `docker-compose.override.yml` to mount the local `python` directory to
+`/home/pi/RASCSI/python/` in the `rascsi_web` container.
+
+Any changes to *.py files on the host computer (i.e. in your IDE) will trigger
+the web UI process to be restarted in the container.
+
+**Example:**
+```
+services:
+  rascsi_web:
+    volumes:
+      - ../python:/home/pi/RASCSI/python:delegated
+```
+
+### Connect the Web UI to a Real RaSCSI
+
+This can be useful for testing, but there are some caveats, e.g. the RaSCSI and the
+web UI will be accessing separate `images` directories.
+
+```
+RASCSI_HOST=foo RASCSI_PASSWORD=bar docker compose up
+```
