Arguments like kubelet_args not properly escaped into script templates

[jrudolph]

I used a setting like

kubelet_args:
  - "eviction-hard=memory.available<200Mi"

which led to the master init script silently failing. The reason is that the shell interprets the < inside of the command line to set up k3s.

Suggestions for improvements:

• either document or properly escape values like this when pasting into scripts
• properly upload script before executing and use set -e to avoid the script running to the end even when steps failed
• better error reporting when something fails

Hi, thanks for reporting this. So you just need to wrap the line in double quotes?

Would you have a chance to open a PR for this?
