Dry-run status code when --force flag is not present

[b4nst]

Currently a dry-run without a force will display something like that for immutable resources

2:20PM ERR i:object-name> Deployment/namesapce/my-app immutable (server dry run)

However it will exit with status 0. Imo this is wrong because if we remove the --dry-run and the object doesn't have the action.timoni.sh/force annotation, the apply will fail.

I propose we show an ERR and exit with an error status (maybe 2 to identify immutable error versus runtime error) if force arg is not used and action.timoni.sh/force is not set on that resource.
If force or action.timoni.sh/force is present, then we can set a WARN or something like this and exit 0.

We do look for the force annotation and we repot the dry run action as created

timoni/cmd/timoni/dyff.go

Lines 106 to 112 in f44c6a8

	if ssa.AnyInMetadata(r, map[string]string{
	apiv1.ForceAction: apiv1.EnabledValue,
	}) {
	log.Info(colorizeJoin(r, ssa.CreatedAction, dryRunServer))
	} else {
	log.Error(nil, colorizeJoin(r, "immutable", dryRunServer))
	}

I agree that we should return a non zero exit code for immutable and without --force.

I'll give it a try this week if I find some time.
