Fixed and improved Docker environment

• Unified Dockerfile:

  • Moved GPU_CHOICE from RUN to ARG instruction so all the Dockerfiles could be unified into a single Dockerfile
  • Added CLI_ARGS to start_linux.sh command (very important fix, without it CLI_ARGS are ignored)
  • Set HOME as global instead of process-specific envvar (so it's also set when entering the container manually)
  • Removed redundant WORKDIR (we've already changed into it)
  • Deleted old Dockerfiles (now obsolete because of the unified Dockerfile)

• Composefiles:

  • Fixed APP_UID variable default (added missing colon)
  • Added sensible container_name ("text-generation-webui" instead of default "text-generation-webui-text-generation-webui-1")
  • Added sensible hostname ("text-generation-webui" instead of random ID)
  • Added restart policy "unless-stopped" (so container can be kept running or stopped properly when starting detached)

• Envfile-Example:

  • Added PYTORCH_KERNEL_CACHE_PATH pointing at cache dir to fix "UserWarning: Specified kernel cache directory could not be created! This disables kernel caching."
  • Added APP_RUNTIME_UID to APP_RUNTIME_GID (so you can not only define the group, but also the user for access to mounted volumes)

• Docs:

  • Create symlinks (fixed) and missing dirs (so they won't be created by Docker as root)

• .gitignore

  • Added .dockerignore

Tested and it works for me. I can now define and use CLI_ARGS="--listen-host 0.0.0.0 --listen" as an env var set in my .env
