Install more dependencies by default

This installs more dependencies by default:

• docker.io: docker cli (if you use dind or /var/run/docker.sock sharing)
• apache2-utils: ab for easy benchmarking
• dnsutils: dig and nslookup
• tcpdump: as sometimes it is helpful to use tcpdump to inspect packets
• net-tools: ss and netstat
• nano, vim: sometimes to edit files
• exiftool: required by workhorse on file uploads
