NFS lease period not implemented #22
Description
In NFS the filehandle returned by OPEN is only valid for the lease period (attribute lease_time which is in seconds). Currently no consideration of this is made, thus after the lease period has ended we start erroring.

It is likely that this is causing the 10025 (NFS4ERR_BAD_STATEID) and 10020 (NFS4ERR_NOFILEHANDLE) NFS errors that occur some time during the workloads.
