Add SCC COCOMO and Complexity Metrics

Expected behavior

The repository metrics report page as well as the org metrics report page should display complexity and COCOMO metrics to communicate cost estimates and complexity to the user. We will use the boyter/scc tool in order to generate this part of the report.

Example output:
