Adding hosts to a cluster fails at stage Failed to create NFS datastore nfs-wld-xxx-temp-ds01"

Issue/Introduction

Adding hosts to a cluster fails at stage "Configure NFS Datastore on ESXi Hosts"

The cluster has one NFS datastore in a datastore cluster, which is added successfully when the SDDC manager tries to add a host to the cluster it fails with the error "Message: Failed to create NFS datastore nfs-wld-###-temp-ds01". The data store does not exist in the vCenter and fails.

The only datastore in the datastore cluster is called "nfs-wld-###-a-ds01", and we cannot find the other datastore "nfs-###-temp-ds01" in  the vCenter
