We used to define domains persistent in libvirt, which caused XML definitions
to stay there after a reboot of the hypervisor.
We however don't do anything with those already defined domains, actually, we wipe
all defined domains when starting the agent.
Some users however reported that libvirt started these domains after a reboot
before the CloudStack agent was started.
By starting domains from the XML description and not defining them we prevent
them from ever being stored in libvirt.
Due to incorrect logic the private network traffic label specified was not getting used, instead some default was getting used (vSwitch0 or privateEthernetPortProfile). The fix passes the correct label in the format vSwitchX or vSwitchX,<vlan_id> and based on that the correct switch is used.
following changes
- introduced notion of event bus with publish, subscribe, unsubscribe
semantics
- a plug-in can implement the EventBus abstraction to provide event
bug to CloudStack

- stream lines, action events, usage events, alerts publishing in to
convineance classed which are also used to publish corresponding
event on to event bus
- introduced notion of state change event. On a state change, in the
state machine corrsponding to the resource, a state change event is
published on the event bug
- associated a state machined with Snapshot and Network objects
- Virtual Machine, Volume, Snaphost, Network object state changes wil
result in a state change event
- Fixed new join dao impls as spring components
- Fixed component context xml to load api rate limit checker
- Fixed root pom.xml for duplicate plugin
