Use function aws.Int64Value replace of deprecated function orZero
**What this PR does / why we need it**:
```
// orZero returns the value, or 0 if the pointer is nil
// Deprecated: prefer aws.Int64Value
func orZero(v *int64) int64 {
return aws.Int64Value(v)
}
```
Use function aws.Int64Value replace of deprecated function orZero and remove unused orZero .

The patch removes ExternalID usage from node_controller
and node_lifecycle_oontroller. The code instead uses InstanceID
which returns the cloud provider ID as well.

Volume deletion should be idempotent
- Describe* calls should return `aws.Error` so caller can handle individual errors. `aws.Error` already has enough context (`"InvalidVolume.NotFound: The volume 'vol-0a06cc096e989c5a2' does not exist"`)
- Deletion of already deleted volume should succeed.

Return missing ClusterID error instead of ignoring it
This fixes issue #57382. In the cases I'm aware of kubelet cannot function if it can't detect the cluster it is running in, so the error should be passed up to the caller preventing initialization when kubelet would fail. This way the error can be detected and kubelet startup attempted again later (giving AWS time to apply the tags).
```release-note
On AWS kubelet returns an error when started under conditions that do not allow it to work (AWS has not yet tagged the instance).

Tag Security Group created for AWS ELB with same additional tags as ELB
/sig aws
(I worked on this with @bkochendorfer)
Tags the SG created for the ELB with the same additional tags the ELB gets from the `service.beta.kubernetes.io/aws-load-balancer-additional-resource-tags` annotation. This is useful for identifying orphaned resources.
We think that reusing the annotation is a simpler and less intrusive approach than adding a new annotation, and most users will want the same set of tags applied.
We weren't sure how to write a test for this because it looks like the fake EC2 code doesn't store the state of the security groups. If new tests are a requirement for merging, we'll need help writing them.
Fixes#53489
```release-note
AWS Security Groups created for ELBs will now be tagged with the same additional tags as the ELB (i.e. the tags specified by the "service.beta.kubernetes.io/aws-load-balancer-additional-resource-tags" annotation.)

Currently the AWS cloud provider uses the EC2 instance role when
interacting with AWS APIs. This change gives the option to provide and IAM
role that the cloud provider will assume before calling the APIs. All
resources created by the role will be owned by that account instead of
the account where the EC2 instance is running.

Make AWS attach/detach operations faster
Most attach/detach operations on AWS finish within 1-4seconds.
By using a shorter time interval and higher exponetial
factor we can shorten time taken for attach and detach to complete.
After this change retry interval looks like:
```
[1, 1.8, 3.24, 5.832000000000001, 10.4976]
```
Before it was:
```
[10, 12.0, 14.399999999999999, 17.279999999999998]
```
/sig aws
```release-note
AWS: Make attach/detach operations faster. from 10-12s to 2-6s
```
The DetachDisk method of AWS cloudprovider indirectly calls
EC2::DescribeVolume AWS API function to check if the volume
being detached is really attached to the specified node.
The AWS API call may fail and return error which is logged however
the DetachDisk then finishes successfully. This may cause the AWS
volumes to remain attached to the instances forever because the
attach/detach controller will mark the volume as attached. The PV
controller will never be able to delete those disks and they need
to be detached manually.
This patch ensures on error from DescribeVolume is propagated to
attach/detach controller and the detach operation is re-tried.
shutdowned -> stopped
use shutdown everywhere
use patch in taints api call
use notimplemented in clouds use AddOrUpdateTaintOnNode
correct log text

add shutdown tests
add context
This adds context to all the relevant cloud provider interface signatures.
Callers of those APIs are currently satisfied using context.TODO().
There will be follow on PRs to push the context through the stack.
For an idea of the full scope of this change please look at PR #58532.
Reuse the
service.beta.kubernetes.io/aws-load-balancer-additional-resource-tags
annotation for these tags.
We think that this is a simpler and less intrusive approach than adding
a new annotation, and most users will want the same set of tags applied.

allow ELB Healthcheck configuration via Service annotations
**What this PR does / why we need it**:
The default settings which are set on the ELB HC work well but there are cases when it would be better to tweak its parameters -- for example, faster detection of unhealthy backends. This PR makes it possible to override any of the healthcheck's parameters via annotations on the Service, with the exception of the Target setting which continues to be inferred from the Service's spec.
**Release note**:
```release-note
It is now possible to override the healthcheck parameters for AWS ELBs via annotations on the corresponding service. The new annotations are `healthy-threshold`, `unhealthy-threshold`, `timeout`, `interval` (all prefixed with `service.beta.kubernetes.io/aws-load-balancer-healthcheck-`)

Add Amazon NLB support
**What this PR does / why we need it**:
This adds support for AWS's NLB for `LoadBalancer` services.
**Which issue this PR fixes** *(optional, in `fixes #<issue number>(, fixes #<issue_number>, ...)` format, will close that issue when PR gets merged)*: fixes #
Fixes#52173
**Special notes for your reviewer**:
This is NOT yet ready for merge, but I'd love any feedback before it is.
This requires at least `v1.10.40` of the [github.com/aws/aws-sdk-go](https://github.com/aws/aws-sdk-go), which is not yet included in Kubernetes. Per @justinsb, I'm waiting on possibly #48314 to update to `v1.10.40` or some other PR.
I tried to make the change as easy to review as possible, so some LoadBalancer logic is duplicated in the `if isNLB(annotations)` blocks. I can refactor that and sprinkle more `isNLB()` switches around, but it might be harder to view the diff.
**Other Notes:**
* NLB's subnets cannot be modified after creation (maybe look for public subnets in all AZ's?). Currently, I'm just using `c.findELBSubnets()`
* Health check uses TCP with all the NLB default values. I was thinking HTTP health checks via annotation could be added later. Should that go into this PR?
* ~~`externalTrafficPolicy`/`healthCheckNodePort` are ignored. Should those be implemented for this PR?~~
* `externalTrafficPolicy` and subsequent `healthCheckNodePort` are handled properly. This may come with uneven load balancing, as NLB doesn't support weighted backends.
* With classic ELB, you have a security group the ELB is inside of to associate Instance (k8s node) SG rules with a LoadBalancer (k8s Service), but NLB's don't have a security group. Instead, I use the `Description` field on [`ec2.IpRange`](https://docs.aws.amazon.com/sdk-for-go/api/service/ec2/#IpRange) with the following annotations. Is this ok? I couldn't think of another way to associate SG rule to the NLB
* Node SG gets an rule added for VPC cidr on NodePort for Health Check with annotation in description `kubernetes.io/rule/nlb/health=<loadBalancerName>`
* Node SG gets an rule added for `loadBalancerSourceRanges` to NodePort for client traffic with annotation in description `kubernetes.io/rule/nlb/client=<loadBalancerName>`
* **Note: if `loadBalancerSourceRanges` is unspecified, this opens instance security groups to traffic from `0.0.0.0/0` on the service's nodePorts**
* Respects internal annotation
* Creates a TargetGroup per frontend port: simplifies updates when you have same backend port for multiple front end ports.
* Does not (yet) verify that we're under the NLB limits in terms of # of listeners
* `UpdateLoadBalancer()` basically just calls `EnsureLoadBalancer` for NLB's. Is this ok?
**Areas for future improvement or optimization**:
* A new annotation indicating a new security group should be created for NLB traffic and instances would be placed in this new SG. (Could bump up against the default limit of 5 SG's per instance)
* Only create a client health check security group rule when the VPC cidr is not a subset of `spec.loadBalancerSourceRanges`
* Consolidate TargetGroups if a service has 2+ frontend ports and the same nodePort.
* A new annotation for specifying TargetGroup Health Check options.
**Release note**:
```release-notes
Add Amazon NLB support - Fixes#52173
