`less -K` makes ctrl+c work with `less`.
When running commands in k9s that use less, sometimes the command doesn't ever return or the user doesn't wait for it to finish. Issuing ctrl+c to a command with a simple `| less` puts k9s into an unfixable state, requiring restarting because `less` never quits. With `less -K`, ctrl+c quits `less` and the user should always be returned to a working `k9s` session.
I also used multiline strings in a few places which improve readability and remove the need for double quotes in many places as many commands had gotten long.
