This patch cleans up pkg/util/mount/* and pkg/util/volume/* to always
use filepath.Join instead of path.Join. filepath.Join is preferred
because path.Join can have issues on Windows.
At times, for some reason endpoint/service creation can fail in a setup. As we
currently create endpoint/service after volume creation, later we need rollback
of this volume transaction if endpoint/service creation failed. Considering
endpoint/service creation is light weight, this patch promote endpoint/service
creation to an early stage.

If the pvc name is more than 63 chars, the endpoint creation
will fail due to the validation of objectmeta length of fields ie 63 chars at max.
This patch introduce an enhancement where if the pvc name is >=63 the pvc uid
is recorded at label instead of name. To preserve backward compatibility, the pvcname
has been kept in endpoint metadata label if length of pvc name is <63chars.

- Move from the old github.com/golang/glog to k8s.io/klog
- klog as explicit InitFlags() so we add them as necessary
- we update the other repositories that we vendor that made a similar
change from glog to klog
* github.com/kubernetes/repo-infra
* k8s.io/gengo/
* k8s.io/kube-openapi/
* github.com/google/cadvisor
- Entirely remove all references to glog
- Fix some tests by explicit InitFlags in their init() methods

This patch introduces glusterfsPersistentVolumeSource addition
to glusterfsVolumeSource. All fields remains same as glusterfsVolumeSource
with an addition of a new field
called `EndpointsNamespace` to define namespace of endpoint in the
spec.

At present, endpoints and services are created
for glusterfs pvcs are in form of glusterfs-dynamic-<PVC name>
however this could cause issue if user deletes a PVC and immediately
creates a new one with the same name, PV controller will try to delete
the old PV and its endpoint and at the same the controller will try to create new PV
and the same endpoint. Depending on which event reaches the
controller first, it may create new PV, check that endpoints exists,
then delete the old PVC and delete endpoints already used by the new PV.
This patch changes the endpoint/service name to below format:
`glusterfs-dynamic-<PVC UUID>`.
By the uniqueness of UUID, above mentioned issue will no longer be present.

The glusterfs plugin/driver set log-level to ERROR by default while
mounting glusterfs shares. However at times, its required to supply other
log-level options like INFO, TRACE..etc. This patch enables the support
to provide other log-level values from storageclass.

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.

At present, `auto_unmount` option is recorded at PV annotation of glusterfs PV.
Due to the preference given in MountOptionFromSpec() for annotation mount options
over sc supplied mount options(Ref PR# https://github.com/kubernetes/kubernetes/pull/66576),
the sc supplied mount options are not honoured in glusterfs plugin
eventhough the driver returns `true` for storage class mountoptions
support at probe.
This patch removes `auto_unmount` option from annotation of the pv spec.
