During host connect multiple listeners gets invoked, one of them is the download listener.
As part of processConnect() method, it checks if templates needs to be downloaded to secondary
store for a particular HV type. As part of that check it computes list of HVs present in the
zone. The earlier logic was to query all hosts (excluding current one) and iterate over them to
make the list. This is not optimal and is bound to have some latency as the number of hosts
increases.
Optimized the logic by querying the list of HVs from the db. directly instead of iterating over
all hosts in the zone.

Initial patch for VXLAN support.
Fully functional, hopefully, for GuestNetwork - AdvancedZone.
Patch Note:
in cloudstack-server
- Add isolation method VXLAN
- Add VxlanGuestNetworkGuru as plugin for VXLAN isolation
- Modify NetworkServiceImpl to handle extended vNet range for VXLAN isolation
- Add VXLAN isolation option in zoneWizard UI
in cloudstack-agent (kvm)
- Add modifyvxlan.sh script that handle bridge/vxlan interface manipulation script
-- Usage is exactly same to modifyvlan.sh
- BridgeVifDriver will call modifyvxlan.sh instead of modifyvlan.sh when VXLAN is used for isolation
Database changes:
- No change in database structure.
- VXLAN isolation uses same tables that VLAN uses to store vNet allocation status.
Known Issue:
- Some resource still says 'VLAN' in log even if VXLAN is used
- in UI, "Network - GuestNetworks" dosen't display VNI
-- VLAN ID field displays "N/A"
The locking code in implement/shutdown network code was not efficient. Even in order to check the current state of the network lock was getting acquired which is not required. This resulted in delays in deploy VM as can be seen from attached logs where the code waited on the lock just to check if network is implemented.
As part of the fix moved out code that is checking if the network is already implemented or shutdowned outside the lock.
For some scenarios like prepare nic, all network service providers are checked which is not efficient and also introduces unnecessary dependencies.
The check to use only the required providers is already there for implement, shutdown operation on network. Put the same check for all missing cases.
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 reverts commit 94254e3c2b.

Regular user should be able to list the network offering with specifyVlan=true. He just can't use when create the network as he is unaware of the physical network topology. But as the admin can create the network on the user's behalf using this kind of offering, so the user should be able to see the offering's details
