Fix bug where Kali does not run user data scripts

[jsf9k]

🗣 Description

This pull request:

• Modifies the Ansible code to no longer manually enable all cloud-init services, but instead only enable cloud-init-main.service
• Modifies the Ansible code to use a DEB822-style repo for Neo4j
• Removes the installation of resyncgg/ripgen

💭 Motivation and context

• Manually enabling all cloud-init services results in warnings from cloud-init. cloud-init-main.service is not currently enabled on Kali Linux but should be. This resolves Kali AMI does not run user data scripts #180.
• Kali Linux is based on Debian Testing and therefore no longer offers apt-key.
• This tool fails to build on the latest version of Kali Linux, and upon checking we learned that it is not being used by assessors.

🧪 Testing

All automated tests pass. I also built a staging AMI, applied it to our COOL staging environment, and verified that it functions as expected.
