Print graph of feature dependencies

[fwilhe]

This adds a new 'graph' command to parse_features. This command prints the text representation of a mermaid js flowchart/graph. This output can be embedded into GitHub flavoured markdown files.

I used the following command to run the script:

builder/builder/parse_features  --feature-dir gardenlinux/features/ --arch `dpkg --print-architecture` --version today --cname kvm graph

where the cname argument can be any feature.
