Handle NPE while setting up data source in Transaction
- This occured as Transaction is called it would run the following which
assumed db.properties file, which may not be in one's classpath;
// Initialize with assumed db.properties file
initDataSource("db.properties");
- So, while this would be logged in logs, this is ignored for DatabaseCreator's
case. In DatabaseCreator we call initDataSource with full path anyway.

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.

The issue happens randomly when hosts in a cluster gets distributed across multiple MS. Host can get split in following scenarios:
a. Add host – MS on which add host is executed takes ownership of the host. So if 2 hosts belonging to same cluster are added from 2 different MS then cluster gets split
b. scanDirectAgentToLoad – This runs every 90 secs. and check if there are any hosts that needs to be reconnected. The current logic of host scan can also lead to a split
The idea is to fix (b) to ensure that hosts in a cluster are managed by same MS. For (a) only the entry in the database is going to be created except in case if the host getting added is first in the cluster (in this case agent creation happens at the same time) and then (b) will take care of connection and agent creation part. Since currently addHost only creates an entry in the db there is a small window where the host state will be shown as 'Alert' till the time (b) is scheduled and picks up the host to make a connection. The MS doing add host will immediately schedule a scan task and also send notification to peers to start the scan task.

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
- A rabbitMQ based plug-in that can interact with AMQP servers to
provide message broker based event-bug
- 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
