chore: only one Dockerfile

[JaeAeich]

Currently we have 2 dockerfile for filer and taskmaster, and with implementation of API we will also have another. This might be pointless as we are packaging all the components of tesk. Which means we will have to install tesk in all of the images and the only change that will be there will be entry point.

I porpose that we have one image that installs tesk, and pass the entrypoint as console script as while using running the image as container. checkout current poetry console script:

[tool.poetry.scripts]
filer = 'tesk.services.filer:main'
taskmaster = 'tesk.services.taskmaster:main'
api = 'tesk.api.app:main'  <-- added after api impl

The .Dockerfile in deployment/comtainer has

###################################################
#   Stage 1: Build wheel                           #
###################################################
FROM python:3.11-alpine AS builder

# Set work directory
WORKDIR /app

# Install poetry
RUN pip install poetry

# Copy source code
COPY . .

# Build wheel
RUN poetry build -f wheel

###################################################
#   Stage 2: Install wheel and create user        #
###################################################
FROM python:3.11-alpine AS runner

# Copy built wheel from the builder stage
COPY --from=builder /app/dist/*.whl /dist/

# Install the application with dependencies
RUN pip install /dist/*.whl

# Create a non-root user
RUN adduser -D -u 1000 filerUser

# Switch to the non-root user
USER filerUser

# Set the working directory
WORKDIR /app

# Entrypoint command
ENTRYPOINT ["filer"]  <-- pass as env

The only diff between both the image is the Entrypoint.

PS: This might be blocked till foca still needs Docker to be able to run.
