[Request] Allow modifying annotations

[jgonera]

I have a deploy script that works more or less like this (simplified version):

kustomize edit set imagetag myimage:$VERSION
kustomize edit add annotation deployTimestamp:$(date -u +"%Y-%m-%dT%H%M%SZ")
kustomize build | kubectl apply -f -

git add .
git commit --message="Deploy $VERSION"
git push origin master

I'm using annotations to be able to force a deploy even if I didn't change anything, but it seems that kustomize edit add annotation will not modify an existing annotation:

Error: annotation deployTimestamp already in kustomization file

Could this behavior be changed? Or maybe I should approach this differently?

Maybe a --force flag. What do yo think? @monopole

@Liujingfang1 Is a --force flag still acceptable? I may find the time to create a PR.

Derailing a bit, I have always found the distinction of edit add and edit set really inconvenient for automation. My expected behavior would be add it if it doesn't exist and and edit it if it does. In that way I would expect a --force flag for other commands like edit set image too.

Thus, would it make sense to add --force to more commands?
