How will this feature flag be used?

[dsu-igeek]

This will be used to enable upload progress monitoring and itemsnapshotters. When it is disabled operations should be the same as currently.

I suppose in this commit there should also be some code to check this flag? like

if features.IsEnabled(velerov1api.UploadProgressFeatureFlag) {
...
} else {
...
}

[dsu-igeek]

That's basically going to be all of the code. I wanted to just get this in early so I could get in the parts that are covered by it without having a dependency.

Please commit the changelog and I'll approve.
