Need shorthand flags for follow and container in app logs

[ashupednekar]

Summary

What change you think needs making.

Changed the follow and container flags to BoolVarP and StringVarP respectively in order to support -f and -c shorthands in the command

Motivation

Please give examples of your use case, e.g. when would you use this.

When checking logs of a container... right now we have to write out the whole flag name..

i.e.
argocd app logs my-app --container my-container --follow --tail 100

This is tedious and inconsistent with other similar utilities like kubectl, docker, etc.

Should be like so..

argocd app logs my-app -c my-container -f --tail 100

So that it's consistent with other cli tools, like so
kubectl logs my-pod -c my-container -f --tail 100

Proposal
How do you think this should be implemented?

Just changed the flag type from BoolVar and StringVar to BoolVarP and StringVarP respectively.

// StringVarP is like StringVar, but accepts a shorthand letter that can be used after a single dash.
// BoolVarP is like BoolVar, but accepts a shorthand letter that can be used after a single dash.
