    ganesha: Include a script to generate epoch value
    
    In a NFS-Ganesha HA cluster setup, for NFS clients to recover state
    succesfully post failover, the NFS-servers should start with a unique
    epoch value.
    
    With NFS-Ganesha 2.3, the service accepts an option "EPOCH_EXEC" which
    takes path of the script, generating epoch value. This script is executed before
    starting nfs-ganesha service so that the generated epoch value is used
    while bringing up the service.
    
    This patch includes the script to be used by nfs-ganesha+gluster setup.
    
    The epoch value is computed as follows -
           - first 32-bit contains the now() time
           - rest 32-bit value contains the local glusterd node uuid
