Upsert operations should tell you if a record was created or updated

[jwoertink]

When you're using an upsert, you may want to know whether the record that comes back was an updated record or a new record.

SaveGoal.upsert(title: "Some goal", amount: 100) do |operation, goal|
  # maybe something like this?
  operation.created? #=> false
  operation.updated? #=> true
end

This could really hook in to all SaveOperation too.

SaveGoal.create(...) do |o, g|
  o.created? #=> true
  o.updated? #=> false
end

SaveGoal.update(...) do |o, g|
  o.created? #=> false
  o.updated? #=> true
end

We already have operation.saved?

avram/src/avram/save_operation.cr

Lines 27 to 28 in 9c8caec

	enum OperationStatus
	Saved

One thing I forgot to consider on this.... What are the results when the save fails? I guess if you're calling create and it fails to create then created? just returns false, and same for updated? 🤔

This is now done.
