Had added deviceDeviceSelector in container_fs* queries as part of kubernetes-mixin PR since diskDeviceSelector includes only node_exporter label values figuring out what all need to be updated to make it work for cadvisor label values as well Because dashboard still gives no datapoints as there is no matching regex for diskDeviceSelector |

container_fs_.* metrics doesn't have "container" label after
/pull/1402 which caused regression
for dashboards using "container" label since it gives empty datapoints
for all queries using "container" label in queries containing
container_fs_.* metrices.
Inorder to fix the dashboards added containerfsSelector in
kubernetes-monitoring/kubernetes-mixin/pull/737 and overrided the containerfsSelector
default value from container!="" to harmless id!="" in this commit.
We really don't need that selector since we dropped the container label
in OCP for container_fs_.* metrices but we need to override the
selector for the queries involving container_fs_.* to work. Dropped the dashboard
"Kubernetes / Compute Resources / Pod" since Prometheus doesn't collect the
per-container fs metrics (discussed in #1685 (comment))
Had added deviceDeviceSelector in container_fs* queries as part of
kubernetes-monitoring/kubernetes-mixin#737 since diskDeviceSelector
includes only node_exporter label values updated disDeviceSelector
to include cadvisor devices too (/dev)
