Adding ability to use IAM roles

[GnatorX]

My issue is: I need to use IAM role when running orchestrator on EC2 rather than IAM user. Since IAM roles are more suited for access control when it comes to running on ec2, i added the ability to use IAM role via env creds.

My Cuckoo version and operating system are: Latest + linux orchestration + window VMs

Hi @GnatorX Do you mean assigning IAM role to the EC2?

[GnatorX]

Not exactly. This is for if you already gave your EC2 Instance an IAM instance profile with an IAM role, this PR will pick up that IAM role
