This changeset is phase one of changing the pollster API to support polling individual instance resources. In this change, the single compute agent is divided into two separate daemons. The compute agent, for polling instance data, is still meant to run on the compute server. The new "central" agent, for polling resources not tied to a compute node, is meant to run on a management server (probably the same place the collector runs). The configuration of the pollsters is updated so that they are loaded by the appropriate agent. New base classes are introduced for each of the types of pollsters. For now, the APIs remain the same. The code implementing the agent and plugins has been moved around to reflect the new logical relationships, and the documentation is updated (including new installation instructions).
