[karthick]

While setting up manila.conf for NFS-ganesha(volume based layout) with gluster as backend m-shr service continuously crashes. Error seen - no such option in group glusterganesh2: glusterfs_path_to_private_key

This issue is however not seen with directory based layout for ganesha.

    glusterfs*: fix ssh credential options

    glusterfs and glusterfs_native had a distinct
    set of options to specify ssh credentials
    (glusterfs_server_password vs glusterfs_native_server_password
    and glusterfs_path_to_private_key vs glusterfs_native_path_to_private_key).

    There is no reason to keep these separate; but worsening the situations
    these options have been moved to layouts in an ad-hoc manner,
    breaking certain driver/layout combos whereby the credential
    option used by the driver is not provided by the chosen layout
    and thus it was undefined.

    Fix all the mess by defining glusterfs_server_password and
    glusterfs_path_to_private_key in glusterfs.common, and
    providing the native variants as deprecated aliases.
