Add availability zones support to Azure managed disks
**What this PR does / why we need it**:
Continue of [Azure Availability Zone feature](https://github.com/kubernetes/features/issues/586).
This PR adds availability zone support for Azure managed disks and its storage class. Zoned managed disks is enabled by default if there are zoned nodes in the cluster.
The zone could also be customized by `zone` or `zones` parameter, e.g.
```yaml
apiVersion: storage.k8s.io/v1
kind: StorageClass
metadata:
annotations:
name: managed-disk-zone-1
parameters:
zone: "southeastasia-1"
# zones: "southeastasia-1,"southeastasia-2"
cachingmode: None
kind: Managed
storageaccounttype: Standard_LRS
provisioner: kubernetes.io/azure-disk
reclaimPolicy: Delete
volumeBindingMode: Immediate
```
All zoned AzureDisk PV will also be labeled with its availability zone, e.g.
```sh
$ kubectl get pvc pvc-azuredisk-az-1
NAME STATUS VOLUME CAPACITY ACCESS MODES STORAGECLASS AGE
pvc-azuredisk-az-1 Bound pvc-5ad0c7b8-8f0b-11e8-94f2-000d3a07de8c 5Gi RWO managed-disk-zone-1 2h
$ kubectl get pv pvc-5ad0c7b8-8f0b-11e8-94f2-000d3a07de8c --show-labels
NAME CAPACITY ACCESS MODES RECLAIM POLICY STATUS CLAIM STORAGECLASS REASON AGE LABELS
pvc-5ad0c7b8-8f0b-11e8-94f2-000d3a07de8c 5Gi RWO Delete Bound default/pvc-azuredisk-az-1 managed-disk-zone-1 2h failure-domain.beta.kubernetes.io/region=southeastasia,failure-domain.beta.kubernetes.io/zone=southeastasia-1

Provide an option to supply log-file mount option for gluster plugin.
At present, `log-file` location of glusterfs client mount is decided
by the plugin, however at times, users/admin want to configure log-file
of gluster fuse client process on their own in some setups. Even though they can pass log-file
mount option through storage class, before this patch glusterfs plugin
always discard it. This patch enable/give preference
to admin supplied log-file mount option if specified in storage class.
If the log-file mount option is incomplete or wrong, plugin fallback to the
location which is carved out by the combination of pvc and pod name.

#!/bin/bash
set -euo pipefail
# set by the node image
unset KUBECONFIG

kubelet: volumemanager: poll immediate when waiting for volume attachment
Currently, `WaitForAttachAndMount()` introduces a 300ms minimum delay by using `wait.Poll()` rather than `wait.PollImmediate()`. This wait constitutes >99% of the total processing time for `syncPod()`. Changing this reduced `syncPod()` processing time for a simple busybox pod with one emptyDir volume from 302ms to 2ms.
