[BeaconBeagle] Connector Add

[Ch-Philou]

Hello,

this connector import data gracefully given freely at https://beaconbeagle.com/
It's "just" CobaltStrike C2 information decoded.

The connector add:

• C2 IPs (v4 and v6) -> create indicators
• if given DomainNames -> create indicators
• URL -> create indicators
• Cobalstrike licence watermark (if requested in parameters)
• Spawned Process (if requested in parameters)
• CobalStrike Software (with version)
• UserAgent (stix2 lib does weird thing with this IoC type... but i got a trick)

Of course it link all this elements with associated Attack Pattern, Tool (given in parameter) and add tags

Optionally, it will make a whois for BGP (whois -h bgp.tools -v {ip_to_check}) to associate C2 IP with:

• Country
• BGP AS (Number and name)

It's obvious but: it works on my OCTI :)

Fixes #6156 6156
