/**
* Validation to add an address to a system
* o = System::class
*
* @note This validation only expects to be used with POST
* Variables:
* + "action" => "node" // type of address being created
* + "zone_id" => "2"
* + "region_id" => "21"
* + "host_id" => "3"
* + "hub_id" => null
* + "node_id" => "9999"
* + "point_id" => "0"
* + "region_id_new" => null // creating a new region id
* + "host_id_new" => null // creating a new host id
* + "node_id_new" => null // creating a new node id
* + "hub" => "0"
* + "security" => "9"
*
* Rules:
* - ZC is z:0/0.0 - region,node,point must be zero
* ZC is identified when region_id,host_id,node_id and point_id === 0
* - RC is z:r/0.0 - region is non-zero, host_id = region_id, node,point must be zero.
* RC is identified when region_id === host_id and, node_id and point_id === 0
* - NC is z:h/0.0 (r=r, r!=h, h!=z) [parent where z:r/0 and h=r, n=0]
* NC is identified when region_id !== host_id and, node_id and point_id === 0,
* - HC is z:h/n.0 (r=r) [parent pointed by hub_id AND validate by z:h/0 is the hub_id]
* HC is a normal node with, but has children pointing to it with hub_id
* - NN is z:h/n.0 when point_id === 0
* A normal node where node_id !== 0, it may or may not have a hub_id
* - PT is z:h/n.p where point_id !== 0
* PT is identified when point_id !== 0;
