cDOT driver creates useless export-policy rule

[cfey]

When using manila with cDOT backend, the manila create command creates a export-policy for every newly created volume and adds a policy rule with "localhost". This is not nessesary.

    NetApp cDOT driver should not create useless export-policy rule

    When using manila with a cDOT backend, the 'manila create' command
    creates an export-policy for every newly created NFS share and adds
    a policy rule with "localhost". This is not necessary.
