kubernetes: Remove deprecated spec.externalID

This got marked as deprecated four years ago [1], and finally removed
last year [2]. This is not present at all any more in Kubernetes 1.12.

This has been identical to `metadata.name` since [1], so just use the
latter directly.

In the nodes overview list, don't show the name/ID again in the Address
column, as that's just redundant: The first column already shows that.
So show the actual address instead.

[2] https://github.com/kubernetes/kubernetes/pull/60692

Closes #11385
