Updating the fix to cover one more scenario when user directly calls API migrateVirtualMachineWithVolume.
If currentPool is accessible to destination host, skip calling allocators and move on to next volume to process.
This means if user calls migrateVirtualMachineWithVolume API where all volumes of VM are accessible on specified target host,
then API fails as there is no storage migration involved. Instead user should call migrateVirtualMachine API.

listHostsForMigrationOfVM is being called when user attempts to move a VM to other host. This is trying to find list of suitable storage pools that are attached to each of the suitable hosts for the VM.
Currently the selection of target storage pools for each volume of the VM is left to storage pool allocators.
But user might want to leave his volume unmoved/intact If it is on a zone wide storage pool.
This would be more efficient while migrating VM as storage live migration is not required and VM continues to use volumes on same storage pool as before.
Hence idea is to set same storage pool as target pool for each of the volume if the volume is already on zone wide storage pool.
A comparison of source pool of volume against target pool of volume yields the information if storage migration is required for the VM to move to target host or not.
Based on that information apropriate API migrateVM or migrateVmWithVolume could be decided.

While upgrading to 4.2, the type of vswitch being used by each cluster is persisted to cluster_details table. This helps if user want to change the type of vswitch used in a zone or entire cloud later on but leave existing cluster continue to use old vswitches. Hence even after modifying the type of vswitch at cloud level (by modifying global configuration parameters) or modifying the type vswitch at zone level (by modifying the traffic label) would not disturb operation of existing clusters.

Introducing the option dhcp-client-update fails if the dnsmasq version is less than 2.6 (like in older templates).
Added a check for the version in cloud-early-config. will add dhcp-client-update option in the config file only
if the dnsmasq version is 2.6 and above.

Simulator should revert back to CLOUD_DB after its operations on
SIMULATOR_DB or the cloudstack connections go to the simulator instead
of cloud.

If all the VM's volumes are on zone wide primary storage pool then live migration of the VM would not involve storage migration. Hence MigrateVM API would be called against MigrateVMWithVolume. So far PrepareForMigrationCommand handled scenarios of VM moving across hosts within a cluster, but with zone wide primary storage in picture this command need to handle scenarios of VM moving across clusters. Try to find the VM in datacenter if not found within cluster.

If you shut down the agent while VMs are running, the management
server assumes that the VMs are continuing to run. You can then
delete the host while it is in 'disconnected' state, and those VMs
will be unusable, forever in running state. They can't change state
because the host no longer exists. This patch checks for any VMs
that may have been tied to the removed host and resets their state
so that cloudstack can continue to manage them.
This is due to a VM on zone wide primary storage not requiring storage migration while migrating across clster.
Detecting the storage pool type before allowing normal migration (without storage live migration) of VM across cluster.
