Adding the zone, cluster, account level parameters
The parameters at scope (zone/cluster/pool/account) can be updated by updateConfiguration API with additional parameter zoneid/clusterid/accountid/storagepoolid
Whenever these scoped parameters are used in CS they get value from the corresponding details table if not defined get value from global parameter.
Same with the listConfiguration API with additional parameter zoneid/clusterid/accountid/storagepoolid
Addition of two new resource types i.e. Primary and Secondary storage space in the existing pool of
resource types.
Added methods to set the limits on these resources using updateResourceLimit
API command and to get a count using updateResourceCount. Also added calls in the
Templates, Volumes, Snapshots life cycle to check these limits and to increment/decrement the new
resource types
Resource Name :: Resource type number
Primary Storage 10
Secondary Storage 11
Also added jUnit Tests for the same.

I made the changes to make sure that:
1. ISO will be deleted from the UI, but it is not deleted from the secondary storage as long as it is attached to a VM.
2. The storage cleanup thread will check whether the iso is attached to any vm, if not, it removes the ISO from the secondary storage.
3. Detach operation is now working which was failing before for the vms having attached iso(deleted).
Updated the patch for template sync during MS restart.
Manually tested the following:
setup: upload ISO1 and ISO 2
Attach ISO1 to VM1 and VM2
Attach ISO2 to VM3
set storage.cleanup.interval to 300
test cases:
1. delete ISO1 from UI, gets deleted
2. In VM Details of VM1 and VM2, can see detach ISO option
3. ISO1 exists in secondary storage
4. detach ISO1 from VM1, successful
5. ISO1 still exists in secondary storage.
6. Restart MS, template sync will not delete ISO1.
7. Detach ISO1 from VM2, successfull detached.
8. Wait for storage cleanup thread to execute, ISO1 gets deleted from Secondary storage.
9. Detach ISO2 from VM3
10.ISO2 exists in secondary storage, Delete ISO2 form UI, get deleted from secondary storage.
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
