Make test-logs.sh more convenient to use

test-logs.sh is convenient to locally test things, this makes it a bit
more convenient to use:
- Make it executable (chmod +x)
- Make it use a virtualenv
- Make it install ARA if it's not installed
- Make it store logs in temporary directories
- Make it use ansible_connection: local instead of a literal SSH
  connection to localhost
