cli: remove deprecated eval status -json list behavior

In Nomad 1.2.6 we shipped `eval list`, which accepts a `-json` flag, and
deprecated the usage of `eval status` without an evaluation ID with an upgrade
note that it would be removed in Nomad 1.4.0. This changeset completes that
work.

+#### `nomad eval status -json` Without Evaluation ID Removed
+
+Using `nomad eval status -json` without providing an evaluation ID was
+deprecated in Nomad 1.2.4 with the intent to remove in Nomad 1.4.0. This option
+has been removed. You can use `nomad eval list` to get a list of evaluations and
+can use `nomad eval list -json` to get that list in JSON format. The `nomad eval
+status <eval ID>` command will format a specific evaluation in JSON format if
+the `-json` flag is provided.
