Upgrade packet requests to use flow objectives API.
Addressed a few issues found while using the flow objectives across a cluster:
* Flow objectives should be installable from any node, not just the master.
Therefore we need to ensure all nodes initialize a driver for each switch.
* We no longer store a list of objectives that are waiting for the switch
to arrive. If the we don't know about the switch yet we'll try a few times
over a few seconds to find it, but after that we'll give up and report an
error to the client.
* Default drivers need to be available when the FlowObjectiveManager starts
up, otherwise it is common to get flow objective requests before any
drivers have been loaded.
