We need to ensure that when converting resource.Quantity
to int64 it does not overflow and if it does, then an error is
returned back to the use rather than attempting expansion and
provisioning operations with scaled value.
persistent-disks for each instance type correctly.
Tested: Verified the kubernetes node object shows correct limits for
various instance types (n1-, c2-, e2-).
This patch removes pkg/util/mount completely, and replaces it with the
mount package now located at k8s.io/utils/mount. The code found at
k8s.io/utils/mount was moved there from pkg/util/mount, so the code is
identical, just no longer in-tree to k/k.
- Rename MapDevice to MapPodDevice in BlockVolumeMapper
- Add UnmapPodDevice in BlockVolumeUnmapper (This will be used by csi driver later)
- Add CustomBlockVolumeMapper and CustomBlockVolumeUnmapper interface
- Move SetUpDevice and MapPodDevice to CustomBlockVolumeMapper
- Move TearDownDevice and UnmapPodDevice to CustomBlockVolumeUnmapper
- Implement CustomBlockVolumeMapper only in local and csi plugin
- Implement CustomBlockVolumeUnmapper only in fc, iscsi, rbd, and csi plugin
- Change MapPodDevice to return path and SetUpDevice not to return path
This patch removes mount.Exec entirely and instead uses the common
utility from k8s.io/utils/exec.
The fake exec implementation found in k8s.io/utils/exec differs a bit
than mount.Exec, with the ability to pre-script expected calls to
Command.CombinedOutput(), so tests that previously relied on a callback
mechanism to produce specific output have been updated to use that
mechanism.
This patch moves fake.go to mount_fake.go, and follows to principle of
always returning a discrete type rather than an Interface. All callers
of "FakeMounter" are changed to instead use "NewFakeMounter()". The
FakeMounter "Log" struct member is changed to not be exported, and
instead only access through a new "GetLog()" method.
This PR fixes the issue mentioned in #83590 for GCE-PD. It uses
WriteVolumeCache API to writes the file system cache to disk during
UnmountDevice in Windows. Linux does not need to explicitly flush cache
because unmount will automatically sync the disk which also flush the
cache.

The PV name is often necessary to build correct symlink paths

This patch refactors pkg/util/mount to be more usable outside of
Kubernetes. This is done by refactoring mount.Interface to only contain
methods that are not K8s specific. Methods that are not relevant to
basic mount activities but still have OS-specific implementations are
now found in a mount.HostUtils interface.
**What type of PR is this?**
/kind cleanup
**What this PR does / why we need it**:
Staging the GCE Cloud Provider as part of KEP [20190125-removing-in-tree-providers](https://github.com/kubernetes/enhancements/blob/master/keps/sig-cloud-provider/20190125-removing-in-tree-providers.md). Staging repo setup here https://github.com/kubernetes/legacy-cloud-providers
Moves the GCE cloud provider implementation to staging.
This is in preparation for moving the cloud provider code out of tree entirely.
However we need it in staging while the code needs to be consumed both in/out of tree.

Minor fix to go.mod.
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.
Since pkg/util/mount is going to move out of k/k, this exported constant
that is Kubernetes specific needed to move somewhere else. Made sense to
move it to pkg/volume/util.
Update GetDeviceNameFromMount in the mount interface to now take a
pluginMountDir argument, which is volume plugin dir with the global
mount path appended to it already.
Currently GCE PD support 128 maximum disks attached to a node for all
machines types except shared-core. This PR updates the limit number to
date.

This PR adds the support for GCEPD volume. For now, it uses a workaround
(https://github.com/pjh/gce-tools) to get disk number in windows for a given GCE PD name.
