Also don't try to return a DriverNetwork with host networking. None will
ever exist as that's the point of host networking: rkt won't create a
network namespace.

 Handle exact namespace match properly when also matched as prefix

Sigh.

This fixes an issue with the nomad namespace inspect and nomad namespace status commands failing to run for namespaces whose names are the start of another namespace's name: for example, foo and foobar. If the argument matches the first possibility returned by prefix exactly, that namespace will be targetted. If no exact match occurs, the behavior is unchanged.

UI: Log streaming

Changed Superset to only return the resource name

Update community.html.erb to include Levant.

This change requests that Levant be added to the Nomad community page. Levant is an open source templating and deployment tool for HashiCorp Nomad jobs that provides realtime feedback and detailed failure messages upon deployment issues. Further details about Levant can be seen on the [jrasell/levant](https://github.com/jrasell/levant) GitHub page.

The Superset method on Resources used to return a string in the format of “[resource name] exhausted”.
This was leading to the output in plan/create job API DimensionExhausted to return keys like
```
"DimensionExhausted": {"cpu exhausted": 1}
```
This was not anywhere documented, however, one of the examples on the website showed it like this.

The other side effect of this is that the CLI formats the strings from the name of the key leading to output like
```
* Dimension "cpu exhausted" exhausted on 1 nodes
```
