Agent

Massive overhaul of agent.py. Consolidated all agent-related Python files into a single agent.py file to:

• Utilize native Python libraries and not depend on third party or custom libraries (like requests).
• Be a single file so it can be easily moved, downloaded, or transferred between systems.
• Bumped agent_config.json's default number_of_threads from 1 to 8.
• Added supported_scan_binaries key to agent_config.json to allow agent's to advertise what scan capabilities they have. This is an inert functionality right now, but will hopefully allow Master to provide dynamic scanning templates based on what scan binaries an agent can support.
• Added version to agent.py to start tracking when agent.py is updated

Master

• Added capability to cancel and pause nmap and masscan scans from Master. No need to kill the process manually on the agents. Currently, the scan status state must be updated in the /scantron-admin/django_scantron/scheduledscan/ endpoint, which is not ideal, because that endpoint should not be interfaced with.
• Added master/scan_results/cancelled directory to hold cancelled scan files in the event they are needed at a future time
• Started tracking process ID of nmap / masscan scans.

Misc

• Added some updates to processing logic in master/scan_results/masscan_json_to_csv.py .
