Incorrect parameters for ontap_7mod and nfs

[ITD27M01]

After deployment of the stack in the cinder settings there is an empty and incorrect settings for ontap_7mode and nfs. For my NetApp v3170 8.1.4P9 without multistore license (no vfilers) I use only nfs and only 7 Mode but fuel cinder netapp plugin adds configuration for:
1. block protocols
2. settings for vfilers
3. CDOT (Clustered DOT):
--------------------------
[cinder_netapp]
netapp_login=cinder
netapp_controller_ips=
netapp_lun_ostype=linux
netapp_vserver=
netapp_server_port=80
nfs_shares_config=/etc/cinder/shares.conf
netapp_sa_password=
thres_avl_size_perc_start=20
reserved_percentage=0
volume_driver=cinder.volume.drivers.netapp.common.NetAppDriver
netapp_enable_multiattach=False
netapp_storage_protocol=nfs
max_oversubscription_ratio=1.0
backend_host=str:netapp
netapp_storage_family=ontap_7mode
volume_backend_name=cinder_netapp
nfs_mount_options=rw,fg,hard,rsize=65536,wsize=65536,nfsvers=3,nointr,timeo=600,tcp
thres_avl_size_perc_stop=60
netapp_vfiler=
netapp_server_hostname=mynetapp
netapp_host_type=linux
expiry_thres_minutes=720
netapp_pool_name_search_pattern=(.+)
netapp_transport_type=http
netapp_password=mypassword
netapp_webservice_path=/devmgr/v2
netapp_lun_space_reservation=enabled
use_multipath_for_image_xfer=True
netapp_copyoffload_tool_path=
--------------------------

This incorrect configuration makes it impossible to create netapp volumes. In the logs cinder error - incorrect api response from backend.

Workaraund - Should delete incorrect settings after deployment and restart cinder-volume service:
--------------------------
[cinder_netapp]
netapp_login=cinder
netapp_server_port=80
nfs_shares_config=/etc/cinder/shares.conf
thres_avl_size_perc_start=20
reserved_percentage=0
volume_driver=cinder.volume.drivers.netapp.common.NetAppDriver
netapp_enable_multiattach=False
netapp_storage_protocol=nfs
max_oversubscription_ratio=1.0
backend_host=str:netapp
netapp_storage_family=ontap_7mode
volume_backend_name=cinder_netapp
nfs_mount_options=rw,fg,hard,rsize=65536,wsize=65536,nfsvers=3,nointr,timeo=600,tcp
thres_avl_size_perc_stop=60
netapp_server_hostname=mynetapp
expiry_thres_minutes=720
netapp_pool_name_search_pattern=(.+)
netapp_transport_type=http
netapp_password=mypassword
use_multipath_for_image_xfer=True
--------------------------

These are the settings that you need to remove:
'netapp_controller_ips'
'netapp_vserver'
'netapp_sa_password'
'netapp_vfiler'
'netapp_copyoffload_tool_path'
'netapp_lun_ostype'
'netapp_host_type'
'netapp_pool_name_search_pattern'
'netapp_webservice_path'
'netapp_lun_space_reservation'

How to reproduce:
Install cinder netapp plugin:
4 | cinder_netapp | 5.0.0 | 4.0.0 | ubuntu (mitaka-9.0)
Configure settings for nfs protocol and ontap_7mode (described above). Start env deployment.
