This changes BGP Controller's event handling from hive hooks and workerpool to hive jobs, mainly to avoid creating resource.Store in the Start() hive hook of the BGP controller. Since creating resource.Store() blocks until the store is initialized, we should avoid calling it in the Start() hive hook to not slow down the startup process and to allow progressing with the startup even when the CRD is not yet installed.

This changes event handling in BGP CP resource.Store wrappers (DiffStore, BGPCPResourceStore) from hive hooks and a goroutine to a hive job, mainly to avoid creating resource.Store in the Start() hive hook. This also makes them wrappers rather than a super set of the resource.Store, exposing only API that is actually used within the BGP CP, and allowing all methods to return an error if the store has not yet initialized. Since creating resource.Store() blocks until the store is initialized, we should avoid calling it in the Start() hive hook to not slow down the startup process and to allow progressing with the startup even when the CRD is not yet installed.
