Expand Linux cheat sheet's Networking section
What does this MR do?
This MR adds several helpful commands to the networking section of our Linux troubleshooting cheat sheet.
ping
traceroute
tcpdump
ip
mtr
Plus commands to check local DNS settings and configuration.
These commands are used by Support and sometimes useful in GitLab Support tickets, but they are not mentioned in our troubleshooting documentation (yet!).
This is the first iteration toward gitlab-com/support/support-team-meta#2432 (closed)
