Feature : Add possibility to only upload changed files

[RossinesP]

Hi,
I am currently using your app to upload a large static folder. The upload takes ~ 15 minutes. The app always uploads all of the static files and I noticed that the underlying library Swift Client has an option to only upload changed files.
Do you plan on adding such feature ? If not, would you have any advice for me to implement it ?
Thanks

I'm going to be working on this soon.

I started trying to fix this, but the underlying swift library is crap. I'm going to migrate to using the openstackSDK and submit a pull request that changes the underlying library entirely to one that is better written and better supported.

Watch this space. :)
