while fixing #87, noticed a couple lines down that if the containers
spec has more than 1 container, the code probably intends to set
Spec.Containers to a list with a single container, but is instead
setting it to an empty list. The very next lines are trying to access
the 1st element of this empty list, which will result in a panic
Pod labels are being set in line 242, and the`podLabels` variable
already contains the extra `"app.kubernetes.io/name": "netbird-router"`
label, so lines 244-246 are effectively just overwriting any labels that
have been set in the crd.
This is blocking us from using this crd because we need a label
disabling istio injection for the peer to work correctly.
