Removed debug Println

[simster7]

An fmt.Println(...) most likely for debug purposes got merged to master causing debug information to be printed to the user on the CLI:

$ argo submit --watch temp.yaml
[{steps1 stepsTempalte {[] []} nil []  nil  nil}]
[{steps2 stepsTempalte {[] []} nil []  nil  nil}]
[{leafA whalesay {[] []} nil []  nil  nil}]
[{leafB whalesay {[] []} nil []  nil  nil}]
[{steps1 stepsTempalte {[] []} nil []  nil  nil}]
[{steps2 stepsTempalte {[] []} nil []  nil  nil}]
[{leafA whalesay {[] []} nil []  nil  nil}]
[{leafB whalesay {[] []} nil []  nil  nil}]
