Collect Kubernetes distribution platform and version

[bjee19]

Problem: We want to collect the Kubernetes distribution platform and version to ensure NGF works well with the most popular platforms and versions.

Solution: Added collection of Kubernetes distribution platform and version.

Testing: Added unit tests. Conducted E2E testing on each of the specified platforms in #1308 to ensure the platform is correctly collected.

Closes #1308

Below is manually gathered values of a node's spec.providerID for different platforms. All nodes of a platform had the same value in the providerID.

aks:
providerID: azure:///subscriptions/…

gke:
providerID: gce:///us-central1-c/

openshift:
providerID: missing

eks:
providerID: aws:///us-west-2c/***

rancher:
providerID: k3s://local-node

k3s:
providerID: k3s://ip-172-16-0-210

kind:
providerID: kind://docker/kind/kind-control-plane

Below is manually gathered values of a node’s Status.NodeInfo.KubletVersion in addition to the server gitVersion response when running kubectl version --v=8. All nodes of a platform had the same value in the Status.NodeInfo.KubletVersion.

aks:
kubletversion: “v1.28.5”
server gitVersion: “v1.28.5”

gke:
kubletversion: "v1.27.8-gke.1067004"
server gitVersion: "v1.27.8-gke.1067004"

openshift:
kubletversion: “v1.24.6+5157800”
server gitVersion: "v1.24.6+5157800"

eks:
kubeletversion: "v1.29.0-eks-a5ec690"
GitVersion:"v1.29.1-eks-508b6b3"

rancher:
kubletversion: “v1.27.6+k3s1”
server gitVersion: "v1.27.6+k3s1"

k3s:
kubletversion: “v1.28.6+k3s2”
server gitVersion: “v1.28.6+k3s2”

kind:
kubletversion: "v1.29.2"
server gitVersion: "v1.29.2”

They are the same except for eks.

@bjee19 I recommend resolving the conflicts, so that we don't need to do another review after resolving

E2E testing results by testing on each platform:

aks: "K8sVersion":"1.25.6","K8sPlatform":"aks”

gke: "K8sVersion":"1.27.8","K8sPlatform":"gke”

openshift: "K8sVersion":"1.29.2","K8sPlatform":"openshift” — NGF fails to deploy on Openshift, so to test this I created a Kind cluster then added the openshift identifier label to the kind node’s Labels. This should suffice testing for openshift. 

eks: "K8sVersion":"1.29.0","K8sPlatform":"eks”

rancher: "K8sVersion":"1.27.6","K8sPlatform":"rancher”

k3s: "K8sVersion":"1.28.7","K8sPlatform":"k3s”

Kind: "K8sVersion":"1.29.2","K8sPlatform":"kind"
