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.
- Move SetUpDevice to BlockVolumeStager
- Move MapPodDevice to BlockVolumePublisher
- Move TearDownDevice to BlockVolumeUnstager
- Move UnmapPodDevice to BlockVolumeUnpublisher
- Implement BlockVolumePublisher only in local and csi plugin
- Implement BlockVolumeUnstager only in fc, iscsi, rbd, and csi plugin
- Implement BlockVolumeStager and BlockVolumeUnpublisher only in csi plugin
- 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 change is needed to make descriptor lock per pod, in the next commit.
If losetup is called for symlink, path in the output for losetup is resolved,
as a result, we can't distinguish which path the lock is taken.
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.
The alpha feature for mount containers is unused, and is
superseded by CSI. By removing it, we can remove a lot of unnecessary
code, and also clean up the mount library even more before moving it out
of tree.
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.

This patch moves the HostUtil functionality from the util/mount package
to the volume/util/hostutil package.
All `*NewHostUtil*` calls are changed to return concrete types instead
of interfaces.
All callers are changed to use the `*NewHostUtil*` methods instead of
directly instantiating the concrete types.
