While running a 3-host K8s v1.11.0 cluster (where all nodes are masters and workers) on Azure,
it appears as though the number of open file descriptors increases steadily over time for
kube-apiserver and kubelet. All other K8s components have low and steady numbers of open file
descriptors.
Heketi is running in the cluster, with Host 0 and Host 1 each having one glusterfs brick. Host 2 has no glusterfs bricks.
