AAI-1923 Problem deleting due to EdgeRules

Issue-ID: AAI-1923

Fixed EdgeRules for ext-aai-info to esr-system-info
Fixed EdgeRules for lan-port-config to dhcp-service

Fixed EdgeRules for pnf to network-resource
Fixed EdgeRules for logical-link to ext-aai-network
Fixed EdgeRules for vpn-binding to ext-aai-network
Fixed EdgeRules for pnf to ext-aai-network
Fixed EdgeRules for connectivity to ext-aai-network
Fixed EdgeRules for lan-port-config to ext-aai-network
Fixed EdgeRules for network-resource to ext-aai-network
Fixed EdgeRules for site-resource to ext-aai-network
Fixed EdgeRules for sdwan-vpn to ext-aai-network
Fixed EdgeRules for device to ext-aai-network
Fixed EdgeRules for wan-port-config to ext-aai-network

Appears to be a problem with this combo in EdgeRules:

- "delete-other-v": "${direction}",
- "prevent-delete": "!${direction}",

Break the dependency by making one of these values "NONE".
