Returns the prefix for the graphite reporter, formatting the prefix with the host name as input.
<p/>
An example of this: <pre>prefix = cluster.%s.mycomponent</pre>
<p/>
Will give: <pre>cluster.localhost.mycomponent</pre>
<p/>
Where localhost is the host name.
<p/>
It will also replace double dots {@code ..} with a single dot {@code .}.

@return The prefix, with the host name appended.
