Update objects when metadata changed

[mynomoto]

I'm using :cache-control metadata for caching purposes but confetti doesn't update objects when the file has not changed and the metadata has. Not sure if it should but it would be nice if it did ;-)
Fell free to close it if this is not a reasonable feature for the library.

All of the syncing is done in the confetti/s3-deploy project. There we're retrieving object summaries which do not contain metadata. This makes diffing on metadata hard. There's an issue in the s3-deploy project to implement a flag to retrieve full object metadata as basis for syncing: confetti-clj/s3-deploy#10

@mynomoto I updated the individual-diff branch mentioned in that issue, if you feel like pulling it across the finish line you're more than welcome to! :)

That was quick! I will take a look on the branch. Thanks!

I'm back to deploying static websites, which means back to confetti 😄
I thought about it from another perspective. If confetti is managing the bucket then adding a force sync option would avoid the need for this feature and the implications on sync performance from what I saw on confetti-clj/s3-deploy#10
What do you think?
