use default UnhealthyPodEvictionPolicy

etcd should use a default UnhealthyPodEvictionPolicy behavior corresponding to the IfHealthyBudget policy. This policy achieves the least amount of disruption, as it does not allow eviction when multiple etcd pods do not report readiness. This can block node drain/maintenance. The cluster administrator should then analyze these pods and decide which one to bring down manually.
