Runs several tests in a docker container against a server that is started out of band of these tests. Cloudflared token also needs to be retrieved out of band. SSH server hostname and user need to be configured in a docker environment file

• Build cloudflared: make cloudflared

• Start server: sudo ./cloudflared tunnel --hostname HOSTNAME --ssh-server

• Fetch token: ./cloudflared access login HOSTNAME

• Create docker env file: echo "SSH_HOSTNAME=HOSTNAME\nSSH_USER=USERNAME\n" > ssh_server_tests/.env

• Run tests: make test-ssh-server
