[FR] Virustotal custom functionality

[dadokkio]

For internal purposes we created an "improved" virustotal analyzer with some customization:

• Add rescan flavour to rescan an hash
• [get_report] Add specific taxonomies if "selected antivirus" didn't recognize the observable
• [get_report] Add the possibility to automatically rescan hash if report is older than specified days
• [get_report] Add the possibility to download sample and add as attachment [always or if "selected antivirus" didn't recognize it]

The new settings gui for the moment is like:

TheHive gui with custom taxonomy and sample as observable:

Note:

• "download sample" requires a private virustotal key, rescan works also with public key
• Rescan and Get_report uses the same taxonomies, so if you use both on same hash you'll have duplicated taxonomies.
