Why this here? Is it different than volumeBindingMode?

[tetianakravchenko]

yes, it was changed in kube-state-metrics v2 - https://github.com/kubernetes/kube-state-metrics/pull/1107/files and reclaimPolicy was renamed to reclaim_policy, and volumeBindingMode to volume_binding_mode

to support both versions of kube-state-metrics I've added this to mapping (< 2.0 - used reclaimPolicy and volumeBindingMode, example - https://github.com/elastic/beats/blob/main/metricbeat/module/kubernetes/_meta/test/ksm.v1.8.0#L1370, versions > 2.0 - https://github.com/elastic/beats/blob/main/metricbeat/module/kubernetes/_meta/test/ksm.v2.0.0#L1545)
