Is your feature request related to a problem? Please describe.

The index page of the report created with --report shows the workflow graph and is in general a bit empty.

Describe the solution you'd like

It would be helpful to have information about e.g. the work directory, start date, start command,...
Additionally an overview of the workflow e.g. tubemap would be an great enhancement here, so that the user has an quick overview of the workflow that was run.
This could be shown on the index page and the workflow could still remain on the workflow page. Here, the user would get further information about the specific rules.
Information that could be included into the metadata:

• Snakemake version
• Git commit of the Snakemake workflow that was used
• Work directory (this has to be discussed again as there should be an option to remove local paths)

Describe alternatives you've considered
