Cache-invalidation : set to on/off depending on ganesha.enable value
Multi-Head NFS-Ganesha servers need upcall (cache-invalidation)
support to notify them in case of any changes to the files in the backend.
Hence, upcall xlator option "features.cache-invalidation" needs to be enabled
when ganesha.enable is set to 'on'. Similarly, this feature needs
to be disabled when ganesha.enable is set to 'off'
This is a back-port of the fix that is merged on master.
