Follow-up from "mount recommendations for NFS in docs"
The following discussion from !27661 (comment 323201761) should be addressed:
We have:
doc/administration/high_availability/nfs.md
doc/administration/high_availability/nfs_host_client_setup.md
And in both of them we talk about server and client side setups! It's confusing. Which one to keep? Do we need them both?
