This CLI command allows the admin user to set up NFS shares so that data are
committed asynchronously to NFS shares. The user can set up this property for

command.
This CLI command sets up NFS server to run in Accelerated mode, where NFS
commit messages are acknowledged asynchronous after receipt.
