Enhance the CLI in order to return the host network in two flavors
(default, verbose) of the `node status` command.
Fixes: #11223.

`allocation.reload()` has differnt semantics for reloading, as it will
reload the record in the background and immediately resolve [1].
By using the stores' findRecord and specifying `backgroundReload:
false`, we make sure we await the response from the server and hereby
have the complete record once we continue in the code.
Using `allocation.reoad()` causes and infinite loop when we upgrade
ember-data to 3.16 (and model fragments to 5.0.0-beta.2).
[1] This is, unless `shouldBackgroundReload` on the adapter returns
false, but it's true by default.
Previously when creating an eval for job deregistration, the eval
priority was set to the default value irregardless of the job
priority. In situations where an operator would want to deregister
a high priority job so they could re-register; the evaluation may
get blocked for some time on a busy cluster because of the
deregsiter priority.
If a job had a lower than default priority and was deregistered,
the deregister eval would get a priority higher than that of the
job. If we attempted to register another job with a higher
priority than this, but still below the default, the deregister
would be actioned before the register.
Both situations described above seem incorrect and unexpected from
a user prespective.
This fix modifies to behaviour to set the deregister eval priority
to that of the job, if available. Otherwise the default value is
still used.
- Making RPC Upgrade mode reloadable.
- Add suggestions from code review
- remove spurious comment
- switch to require(t,...) form for test.
- Add to changelog
As we have continued to see reports of #9506 we need to elevate this log
line as it is the only way to detect when plans are being *erroneously*
rejected.
Users who see this log line repeatedly should drain and restart the node
in the log line. This seems to workaorund the issue.
Please post any details on #9506!
Log the failure error when the agent fails to start. Previously, the
agent startup failure error would be emitted to the command UI but not
logged. So it doesn't get emitted to syslog or `log_file` if they are
set, and it makes debugging much harder. Also, logging the error again
before exit makes the error more visible: previously, the operator
needed to scroll to the top to find the error.
On a sample failure, the output will look like:
```
==> WARNING: Bootstrap mode enabled! Potentially unsafe operation.
==> Loaded configuration from sample-configs/config-bad

```
This change adds the final `ERROR` message. It's easy to miss the `==>
Error starting agent` above.
