Add ip_addr as a secondary IP address to an address group which belongs to the same subnet.
Edge appliance requires that a VIP will be configured as a primary or a secondary IP address on an interface. To do so, we locate an interface which is connected to the same subnet that vip belongs to. This can be a regular interface, on a sub-interface on a trunk.
Delete ip_addr from secondary address list in address groups.
While removing vip, delete the secondary interface from Edge config.
Edge assigns an ID for each resource that is being created: it is postfixes the uri specified in the Location header. This ID should be used while updating/deleting this resource.
Lookup an address group with a matching subnet to ip_addr. If found, return address_group.
Look for the resource name of the edge hosting the LB.
For older loadbalancers this may be a router edge
Grab the id of an Edge appliance that is connected to subnet_id.
