Support a HTML report in the dashboard

TODO:

• Implement in stryker dashboard
• Implement in dashboard reporter Stryker
• Implement in dashboard reporter Stryker.NET
• Implement in dashboard reporter Stryker4s
• Advertise this in the dashboard

We should implement this in the different reporters behind a flag IMHO. Maybe people only want the mutation score badge and not the full report.

This is supported by #117 although not yet advertised. We should now implement it in each Stryker implementation

This is an example curl:
