Suri socket mode fix; poor-man's auth

[whartond]

• Moved to using Docker Compose Version 2 in start-dalton.sh
• Added functionality for users to set username, along with simple shared auth (see dalton.conf)
• Updated queue page to display user who submitted the job (if so configured)
• Fixed support for Suricata Socket Control in Suricata version 8 and later.
  The necessary Python libraries for suricatasc are no longer included with the Suricata
  source beginning with Suricata version 8.
• Updated docker-compose to have more recent versions of the Suriata and Zeek agents by default
