* Support for the ZAP Scan report. To use it, in the project definition, create the metric source:
`ZAP_SCAN_REPORT = metric_source.ZAPScanReport()`
Add the metric source to the project:
`PROJECT = Project(..., metric_sources={metric_source.ZAPScanReport: ZAP_SCAN_REPORT})`
And then specify for each product the security requirement and where its ZAP Scan report can be found:
`PRODUCT = Product(requirements=[requirement.OWASP], metric_source_ids={ZAP_SCAN_REPORT: 'http://url/to/report.html'}`
This will cause the report to contain to new metrics: `metric.HighRiskZAPScanAlertsMetric` and
`metric.MediumRiskZAPScanAlertsMetric`.
