Add Nameservers to Subnet structure

[poulpreben]

I've added Nameservers to go-phpipam-sdk, and added the corresponding enhancements to the Terraform provider structure. The result looks like this:

# data.phpipam_subnet.test:
data "phpipam_subnet" "test" {
    allow_ip_requests      = false
    create_ptr_records     = false
    description            = "NNN-126"
    description_match      = "NNN-126"
    display_hostnames      = false
    edit_date              = "2022-06-17 10:38:12"
    gateway                = {}
    gateway_id             = "714"
    host_discovery_enabled = false
    id                     = "135"
    include_in_ping        = false
    is_folder              = false
    is_full                = false
    linked_subnet_id       = 0
    location_id            = 0
    master_subnet_id       = 134
    nameserver_id          = 4
    nameservers            = {
        "description" = ""
        "editDate"    = ""
        "id"          = "4"
        "name"        = "External Nameservers"
        "namesrv1"    = "XXX.YYY.76.60;XXX.YYY.76.76"
        "permissions" = "1;3"
    }
    permissions            = jsonencode(
        {
            "2" = "3"
        }
    )
    scan_agent_id          = 0
    section_id             = 3
    show_name              = false
    subnet_address         = "XXX.YYY.79.0"
    subnet_id              = 135
    subnet_mask            = 26
    utilization_threshold  = 0
    vlan_id                = 54
    vrf_id                 = 0
}

As such, it is now possible to add the semicolon separated list of nameservers using data.phpipam_subnet.my_subnet.nameservers.namesrv1.
