Add Spy daemon

[haylinmoore]

Spy is a controller daemon running on each hypervisor. At first it will just be used to start, stop, and get the status on virtual machines, but in the future will be expanded to create and delete virtual machines.

Todos before merging:

• [x] Create spy
• [x] Ansible scripts for install
• [ ] Create Spy update workflow
• [ ] Integration with backend
• [ ] Integration with frontend
