kubectl analyze better output for remove and delete list

[johscheuer]

What would you like to be added/changed?

Currently when running the kubectl analyze command with the --auto-fix flag the command will print out a list of process groups to replace and a list of Pods to delete. Currently this prints out the slice and if multiple process groups/Pods are affected the output can get pretty long instead we might want to consider printing the strings separated by newlines. Something like:

Process groups to replace:
- t1
- t2
- t3
- t4
