Clearing out the client-ca-file option **What this PR does / why we need it**: kubernetes-master charm wouldn't clear the ca-client-file snap setting. We haven't used it for a while, but since it wasn't clearing it out any old deploys that updated would still have it set. This change will start clearing it. **Which issue(s) this PR fixes** *(optional, in `fixes #<issue number>(, fixes #<issue_number>, ...)` format, will close the issue(s) when PR gets merged)*: Fixes # https://github.com/juju-solutions/bundle-canonical-kubernetes/issues/515 **Special notes for your reviewer**: **Release note**: ```release-note kubernetes-master charm now properly clears the client-ca-file setting on the apiserver snap ```
