<p>Multiple instances that are connected to the same underlying repository are
commonly referred to as a 'Cluster'. The reasoning behind this terminology
being that they access the same data and can thus deliver or modify the same
data.</p>
-<p>In the discovery API this cluster concept is represented via a
<code>ClusterView</code> object. A 'view' because it is a momentary snapshot of
the cluster and only contains instances that are currently alive. It's features
are:
-<em> each cluster has a stable leader. Stable meaning it won't change unless
that leader crashes.
-</em> it has a list of instances that are part of it, thus currently alive
