netapp dataontap NFS manage operation fails w/ ipv6 volume reference
When running a "cinder manage" operation of a volume that is on an IPv6 NFS export, _convert_vol_ref_share_name_to_share_ip() in nfs_base.py splits on ':' which does not work if using an IPv6 address in the volume reference.
This results in an error shown below, because the first part of the address is passed to resolve_hostname().
