Currently a model of the cluster is constructed every time a strategy is
executed, which will not scale in production or in larger environments.
If Watcher intends to be used by larger envirionments it needs a more
robust way to construct and maintain a model of the cluster. An
in-memory cache of this model can be built up and kept fresh via
notifications from services of interest in addition to periodic syncing
logic.
