🌱 Remove metadata key with empty value in cluster template (#2008)

remove metadata key with empty value in cluster template

In `v1beta2` the `metadata` field present in Cluster object's
`.spec.topology.controlPlane.metadata` and
`.spec.topology.workers.machineDeployments[].metadata` should not be
specified with a zero value `{}`. As the field now contains the marker
`omitzero`.
