cluster-health crashes upon run

```
-e \e[1m\e[39mTop Pods According to CPU Limits:\e[21m
usage: grep [-abcDEFGHhIiJLlmnOoqRSsUVvwxZ] [-A num] [-B num] [-C[num]]
	[-e pattern] [-f file] [--binary-files=value] [--color=when]
	[--context[=num]] [--directories=action] [--label] [--line-buffered]
	[--null] [pattern] [file ...]
```

It also prints ANSI escape codes (despite the terminal supporting them)
