Change in ovirt-engine[master]: PendingResourceManager for tracking resources in WaitForLaunch

Roy Golan has submitted this change and it was merged. Change subject: PendingResourceManager for tracking resources in WaitForLaunch ...................................................................... PendingResourceManager for tracking resources in WaitForLaunch This patch adds a new scheduler component PendingResourceManager. This manager is responsible for keeping track of all resources that are allocated by not-yet running VMs. Each resource type is represented by its own class type (and values) and can compute summary information about pending counts/sizes per host. This should allow us to easily track multiple resources we lack today - VMs themselves (for affinity or PCI passthrough), VNICs and others. The benefit of this patch is that multiple calls to PRM.cleanVm() do not cause the counters to be decremented multiple times. The manager tracks all pending resources separately and has indexes for per VM and per Host access. The old VDS fields for pending memory and CPU are left in the entity for cache purposes. Reading them does not guarantee validity though. Only SchedulingManager's instance of PRM guaranteed up-to-date and valid values. The only procedure which is allowed to put those to DB is the VdsManager via PendingResourceManager. VdsManager has a new call updatePendingData to receive the current pending values from PRM.
