    Use nfs_oversub_ratio when reporting pool capacity

    Currently NetApp NFS drivers do not make use of the nfs_oversub_ratio
    configuration parameter to enable OpenStack administrators to report
    anything other than the most conservative capacity and usage information
    up to the scheduler

    This commit:
      * modifies the NetApp drivers to use the nfs_oversub_ratio as
         documented.
      * uses direct API with filers to gather capacity information rather
         than stat and du commands
      * brings our reporting of reserved percentage in line with the way
         the scheduler actually makes use of this statistic
      * simplifies and cleans up the way we gather and report pool statistics

    Note that this fix addresses an in-the-field bug report from juno
    and is intended to be the basis for backported fixes.

    In kilo, a more general approach to overprovisioning using
         max_oversubscription_ratio
    was introduced via commit 3548a4bc9edbb26b248b5af5ecc2145f2c6f7481.
    In this newer approach, the scheduler computes "virtual" free space
    rather than the driver reporting "apparent" free space.

    This fix to bring NetApp NFS drivers into conformity with the generic
    NFS driver is not intended as a substitute for introducing support
    in our drivers for the newer approach to overprovisioning. Rather,
    it is a bug-fix for an existing failure to honor the nfs_oversub_ratio.

We need to add the netapp driver as category for the nfs_oversub_ratio option in the flagmappings.
