* moved all services to the separate table, map them to the network_offering+provider.
* added state/securityGroupEnabled properties for the networkOffering
* added ability to list by state/securityGroupEnabled in listNetworkOfferings api command
2) New service: SourceNat
Changes:
- Added a new interface 'PluggableService'
- Any component that can be packaged separately from cloudstack, can implement this interface and provide its own property file listing the API commands the component supports
- As an example have made VirtualNetworkApplianceService pluggable and a new configureRouter command is added
- ComponentLocator reads all the pluggable service from componentLibrary or from components.xml and instantiates the services.
- As an example, DefaultComponentLibrary adds the pluggable service 'VirtualNetworkApplianceService'
- Also components.xml.in has an entry to show how a pluggable service can be added, but it is commented out.
- APIServer now reads the commands for each pluggable service and when a command for such a service is called, APIServer sets the required instance of the pluggable service in the coomand.
- To do this a new annotation '@PlugService' is added that is processed by APIServer. This eliminates the dependency on the BaseCmd to instantiate the service instances.
Since we would introduce a way to specify each service provider in the network
offering, it's better for redundant virtual router as a separate service
provider.
Also isRedundant() flag in the network offering would be removed. Redundant
virtual router temporality won't work from now. Until we're able to add
different network elements/service providers in network_offering.
In the past, the NetworkElement would cover almost all the functionality that
e.g. virtual router can cover: firewall, source NAT, static NAT, password,
VPN... So anyone want to implement the NetworkElement would have to implement
these service's specific methods, even it wouldn't support it. Also, if we want
to find a e.g. FirewallServiceProvider, we have to proceed all the current
network service providers, to call a method to know if it support such service.
That's neither elegant nor scaling way to do it.
As the first step, this patch separates each ServiceProvider from NetworkElement
(there are some interface already out of NetworkElement, so this patch slightly
modifies them too), and only the class would implement the correlated interface, would
have the ability to do these services.
Changes:
- VirtualMachineMgr puts the constraint that if Root volume is already READY, we provide the clusterId in the plan to the deploymentPlanner. Planner then searches for resources only under that cluster.
- If no deployment could be found, deploying VM fails.
- Fixed this, such that incase the root volume is recreatable, we call the planner again by removing the cluster constraint. Planner will then search for resources in other clusters.
- Works for system VMs(SSVM, consoleproxy, virual routers).
This reverts commit 42ab3c94c210d5a29289a5dfd0e44ae99c427f8b.
The commit may not fit for our new network as service framework, because we
would make single router and redundant router as two different service provider,
so the change of network offering should clean up the old network and then setup
new one. Make single router work as redundant router later make no sense in such
condition.
Then every router would have one guest ip. The gateway ip would be used if the
router is not redundant, otherwise the guest ip would be used for guest network.
Changes:
- We were ordering clusters based on capacity of the first-fit host found in each cluster. Due to this, there were cases where we deployed VMs to one cluster instead of balancing off within clusters.
- Now we order the list of clusters by aggregate capacity and choose the ones that have enough capacity for the required VM in this order.
- This should balance the load between clusters instead of bombarding one.

Changes:
- Added a new API 'migrateSystemVm' backed by MigrateSystemVMCmd.java to migrate system VMs (SSVM, consoleproxy, domain routers(router, LB, DHCP))
- This is Admin only action
- The existing API 'migratevirtualmachine' is only for user VMs
