token is hostPath instead of emptyDir + ssh authorized_key nil error

[antoinetran]

Short Description of the issue

1. In OIDC mode, the refresh token shared between vk and refresh-token is now in hostPath:/tmp (see https://github.com/interTwin-eu/interlink-helm-chart/blob/main/interlink/templates/virtual-kubelet.yaml#L160), instead of emptyDir as before (0.3.1-rc2). This causes me a regression because after each deployment, I need to delete the refresh token manually.
2. by default, when ssh bastion is not enabled, the secret regarding the authorized_key is still created, but because it is empty, the kubectl apply gives an error because of nil value.

Should be solved now. Default is emptyDir and the secrets should not be created anymore when ssh bastion is disabled
