GKE host does not have lvmetad

[TonyBogdanov]

According to this line: https://github.com/gluster/gluster-containers/blob/c98eefc6ef90149c93c48061a93766cca5c19a35/CentOS/Dockerfile#L62 we should mount /run/lvm from the host node and not rely on lvm2-lvmetad.service within the container.

Why is that? And also, on GKE neither cos_containerd nor ubuntu_containerd have this service running, so mounting /run/lvm does nothing. How should we proceed in this case?
