The iptables-alerter daemonset does not tolerate custom taints in RHOCP 4.

Issue

• The iptables-alerter DaemonSet should be able to tolerate custom taints to ensure full monitoring coverage across all nodes.
• The openshift-network-operator/iptables-alerter DaemonSet is failing to deploy pods on nodes that have custom taints (e.g., infra nodes).
• Creating a monitoring gap, as nodes with custom taints are not being checked for the creation of deprecated iptables rules.
