Align with new server feature (project creation not creating a dataset by default)

[tcompa]

Requires:

• Remove automatic creation of default dataset when creating a project fractal-server#674
• Align with fractal-server new feature (project creation does not create a dataset) fractal-client#565

As a by-product of this change, it turns out that our examples should get simpler, rather than more complex.

Current version

# Create project
OUTPUT=`fractal --batch project new $PROJECT_NAME`
PROJECT_ID=`echo $OUTPUT | cut -d ' ' -f1`
DS_IN_ID=`echo $OUTPUT | cut -d ' ' -f2`
echo "PROJECT_ID=$PROJECT_ID"  # Do not remove this line, it's used in fractal-containers
echo "DS_IN_ID=$DS_IN_ID"

# Update dataset name/type, and add a resource
fractal dataset edit --new-name "$DS_IN_NAME" --new-type image --make-read-only $PROJECT_ID $DS_IN_ID
fractal dataset add-resource $PROJECT_ID $DS_IN_ID $INPUT_PATH

# Add output dataset, and add a resource to it
DS_OUT_ID=`fractal --batch project add-dataset $PROJECT_ID "$DS_OUT_NAME"`
echo "DS_OUT_ID=$DS_OUT_ID"

fractal dataset edit --new-type zarr --remove-read-only $PROJECT_ID $DS_OUT_ID
fractal dataset add-resource $PROJECT_ID $DS_OUT_ID $OUTPUT_PATH

Future version (to be checked):

# Create project
PROJECT_ID=`fractal --batch project new $PROJECT_NAME`
echo "PROJECT_ID=$PROJECT_ID"  # Do not remove this line, it's used in fractal-containers

# Add input dataset
DS_IN_ID=`fractal --batch project add-dataset $PROJECT_ID "$DS_IN_NAME" --type image`
echo "DS_IN_ID=$DS_IN_ID"
fractal dataset add-resource $PROJECT_ID $DS_IN_ID $INPUT_PATH

# Add output dataset
DS_OUT_ID=`fractal --batch project add-dataset $PROJECT_ID "$DS_OUT_NAME" --type zarr`
echo "DS_OUT_ID=$DS_OUT_ID"
fractal dataset add-resource $PROJECT_ID $DS_OUT_ID $OUTPUT_PATH
