Support for automatic issue creation

[prabhu]

It will be nice to create issues on GitHub, GitLab etc automatically from the sarif and depscan files generated by scan. I'm thinking of adding a new command called reporter and an argument called --report to enable this functionality. The functionality will support some features with sane defaults:

1. Quantity - Single aggregated issue or 1 issue per severity
2. Filters based on category, tool name, and type
3. Severity
4. Git branch (Eg: master only)

Time permitting, I will also include integrations with Jira, clubhouse and Trello.
