kubectl run -it does not work with offloaded pods

[giorio94]

What happened:

Trying to run a pod in a remote cluster through kubectl run -it ... did not result in the shell correctly attached, and instead led to a pod in CrashLoopBackoff status.

What you expected to happen:

The shell should be attached correctly to the remote pod.

How to reproduce it (as minimally and precisely as possible):

1. liqoctl offload namespace default --pod-offloading-strategy=Remote
2. kubectl run ubuntu --image=ubuntu -n default -it --rm -- /bin/sh
3. Observe that the shell is not attached correctly

Anything else we need to know?:

The kubelet emitted the following log line:

I1207 18:53:11.207826       1 klogv2.go:71] 404 request not found [uri=/attach/default/ubuntu/ubuntu?input=1&output=1&tty=1 vars=map[]]

Environment:

• Liqo version: 0.3.2-beta1
• Kubernetes version (use kubectl version): 1.21.0
• Cloud provider or hardware configuration: Kubeadm (on premise)
• Network plugin and version: Calico
• Install tools: liqoctl + helm
• Others: None
