changelog, charts.yaml, kubectl updates for v0.11.0

[tesshuflower]

Describe what this PR does

updates to changelog, charts.yaml and kubectl volsync.yaml now that we've published v0.11.0.

I should probably cherry-pick this into release-0.11 as well.

Is there anything that requires special attention?
