At master volume reconciler, the information about which volumes are
attached to nodes is cached in actual state of world. However, this
information might be out of date in case that node is terminated (volume
is detached automatically). In this situation, reconciler assume volume
is still attached and will not issue attach operation when node comes
back. Pods created on those nodes will fail to mount.
This PR adds the logic to periodically sync up the truth for attached volumes kept in the actual state cache. If the volume is no longer attached to the node, the actual state will be updated to reflect the truth. In turn, reconciler will take actions if needed.
To avoid issuing many concurrent operations on cloud provider, this PR
tries to add batch operation to check whether a list of volumes are
attached to the node instead of one request per volume.

vSphere cloud provider: re-use session for vCenter logins
This change allows for the re-use of a vCenter client session. Addresses #34491
We had another bug where we confused the hostname with the NodeName.
To avoid this happening again, and to make the code more
self-documenting, we use types.NodeName (a typedef alias for string)
whenever we are referring to the Node.Name.
A tedious but mechanical commit therefore, to change all uses of the
node name to use types.NodeName
Also clean up some of the (many) places where the NodeName is referred
to as a hostname (not true on AWS), or an instanceID (not true on GCE),
etc.
Addresses #33215.
When vCenter returns error vm not found, this is now being translated to
the appropriate error 'cloudprovider.InstanceNotFound' which indicates
to Kubernetes node controller that the VM is in fact not found.

vSphere Cloud provider null pointer exception
This PR addresses issue #31823.
SelectByType function in govmomi will panic if deviceType is not Array,
Chan, Map, Ptr, or Slice. Also checking if vmDevices or vm are nil,
there is nothing to cleanup.

Make a vSphere cluster the failure_zone
vSphere cloud provider returns the FailureZone as Cluster, if the VM belongs to a ResourcePool under a Cluster.
fixes: #30933
* Currently the vSphere cloud provider treats Datacenter as the failure
Zone. This doesn't necessarily work since in the current implemention
Kubernetes nodes cannot span Datacenters.
* This change introduces Clusters as the failure zone, while treating
Datacenters as Regions
* Also updated tests for Zones

Run goimport for the whole repo
While removing GOMAXPROC and running goimports, I noticed quite a lot of other files also needed a goimport format. Didn't commit `*.generated.go`, `*.deepcopy.go` or files in `vendor`
This is more for testing if it builds.
The only strange thing here is the gopkg.in/gcfg.v1 => github.com/scalingdata/gcfg replace.

This allows the user the set "working-dir" in their vsphere.cfg file.
The value should be a path in the vSphere datastore in which the
provider will look for vms.

vSphere provider - Getting node data by ip instead of uuid
To get the uuid we need the service to be running as root. This change
allows us to run the controller-manager and api server as non-root.
Hot attach of disk to a scsi controller will work only if the
controller type is lsilogic-sas or paravirtual.This patch filters
the existing controller for these types, if it doesn't find one it
creates a new scsi controller.
- replaces probeVolume with scsiHostRescan to scan hot attached disks
- fixes substring match of UUID returned from AttachDisk
- changes DetachDisk to take volumePath argument instead of diskID
- fixes delayed failure at mount rather than attach disk
- removes cloning of virtual disk in AttachDisk
When vSphere cloud provider object is instantiated, the VM name of the
Node where this object is being create in needs to be set. This patch
also includes vSphere as part of the cloud provider package.
This patch includes implementation for the following Instance object
interfaces:
* NodeAddresses
* ExternalID
* InstanceID
Also minor refactoring in overall Instance implementation.
