Node drain Experiment is failing when passing multiple nodes with comma separated values.

Litmus Experiment - Node Drain is failing when passing multiple node name "NODE1,NODE2".
I observe there might be some code change required for node drain experiment to split comma separated nodes for the experiment to run successfully.

import "strings"

// Assuming `experimentsDetails.TargetNode` holds the comma-separated node names
nodes := strings.Split(experimentsDetails.TargetNode, ",")

for _, node := range nodes {
    trimmedNode := strings.TrimSpace(node)
    // Now perform the drain operation for each node
    log.Infof("Draining node: %s", trimmedNode)
    // You would likely call a function here that orchestrates the drain operation
    err := performNodeDrain(trimmedNode, clients)
    if err != nil {
        log.Errorf("Failed to drain node %s: %v", trimmedNode, err)
        // handle error, possibly abort or continue based on your requirements
    }
}

Maybe we need to add something like the above code in order to fix the issue, Please check and provide the fix as soon as possible.

I have noticed this PR, but I'm wondering why it hasn't been merged into the master branch yet, especially since it pertains to an important Chaos Experiment.
