Can't update peer-cidr in created ipsec site connection in CLI for VPNaaS

[Kristina Berezovskaia]

Can't update peer-cidr in created ipsec-site-connection in CLI. But peer-cidr ipcec-site-connection can be updated in Horizon

Steps to reproduce:
1) Create new IKE Policy: neutron vpn-ikepolicy-create test_ike_policy
2) Create IPSec Policy: neutron vpn-ipsecpolicy-create test_ipsec_policy
3) Create VPN Service: neutron vpn-service-create --name test_service router04 net04__subnet
4) Create IPSec Service Connection: neutron ipsec-site-connection-create --name test_connection --vpnservice-id <vpn_service_id> --ikepolicy-id <ike_policy_id> --ipsecpolicy-id <ipsec_policy_id> --peer-address 172.18.161.181 --peer-id 172.18.161.181 --peer-cidr 10.10.10.1/24 --psk key
5) Update test_connection: neutron ipsec-site-connection-update <ipsec_service_connection_id> --peer-cidr 10.10.20.1/24

The ipsec-site-connection hasn't been updated with error message "Bad Request (HTTP 400) (Request-ID: req-a29c5794-6f0d-44b8-a9c2-f9e579547866)"

For the neutron ipsec-site-connection-update command you should use --peer-cidrs flag instead of --peer-cidr

neutron ipsec-site-connection-update <ipsec_service_connection_id> --peer-cidrs 10.10.20.1/24
