Non static method should not be called statically

[Hoto-Cocoa]

Hi.

I saw you already closed related issue #19. But please check this issue.

Your functions doesn't marked as static method, but your README example wrote in static method usage.

It causes warning in PHP.

I confirmed that code works in static or non-static both. But class doesn't have constructor, so I think It will be called by static way always.

How about add static keyword to functions? Maybe I can open PR to this but you closed related issue in past so I open this issue first.

Thanks.

Hello in PHP 8.0. & 8.1. is this Nodes::setLxcFirewallOptions not allowed, there you have to do it like this: $Nodes->setLxcFirewallOptions

Complete example Create VM

require __DIR__ . '/vendor/autoload.php'; // Autoload files using Composer autoload
use Proxmox\Request;
use Proxmox\Cluster;
use Proxmox\Nodes;

$Nodes = new Nodes(); // NEW LINE
$Cluster = new Cluster(); // NEW LINE

$configure = [
  'hostname' => '0.0.0.0',
  'username' => 'root',
  'password' => 'password',
];
Request::Login($configure); // Login ..

# Create VM
// $nextId = Cluster::nextVmid(); get next vmid - OLD LINE
$nextId = $Cluster->nextVmid(); // get next vmid - NEW LINE
$create = [
  'vmid'        => $nextId->data,
  'cores'       => 1,
  'name'        => 'testApi',
  'scsi0'       => 'local:32,format=qcow2'
];
# Get first node name.
// $firstNode = Nodes::listNodes()->data[0]->node; - OLD LINE
// print_r( Nodes::createQemu($firstNode, $create) ); - OLD LINE

$firstNode = $Nodes->listNodes()->data[0]->node; //  NEW LINE
print_r( $Nodes->createQemu($firstNode, $create) ); //  NEW LINE
