The new policy is:
1. Generate a random IP.
2. Find the next available IP, start from the generated IP.
3. If we cannot find an available IP after certain times(10000 by default,
network.ipv6.search.retry.max) retry, give up.
The basic idea behind this is, deploy a fix sized threadpool for updating RvR
status, then using producer/consumer model. There is a global configuration
router.check.poolsize(10 by default) to control the pool size.
Using pool size 100 for 1000 RvR is tested with simulator and works well.
Also we can adjust the global configuration option router.check.interval to e.g.
60s from default 30s to mitigate the issue.
This is improvement of:

bug 14042: Don't set dhcp:router option on DHCP server for non-default
network on CentOS/RHEL
The old solution only works on CentOS/RHEL, this one would enable the ability to more
guest OS, and enable user to choose what policy should be for each guest os
type.
Support for local data disk. Currently enable/disable config is at zone level, in subsequent checkins it can be made more granular.
Following changes are made:
- Create disk offering API now takes an extra parameter to denote storage type (local or shared). This is similar to storage type in service offering.
- Create/delete of data volume on local storage
- Attach/detach for local data volumes. Re-attach is allowed as long as vm host and data volume storage pool host is same.
- Migration of VM instance is not supported if it uses local root or data volumes.
- Migrate is not supported for local volumes.
- Zone level config to enable/disable local storage usage for service and disk offerings.
- Local storage gets discovered when a host is added/reconnected if zone level config is enabled. When disabled existing local storages are not removed but any new local storage is not added.
- Deploy VM command validates service and disk offerings based on local storage config.
- Upgrade uses the global config 'use.local.storage' to set the zone level config for local storage.

Description:
Code changes to manage Cisco Nexus 1000v in CloudStack.
VmwareResource has been modified to leverage Nexus vSwitch.
Providing following global configuration parameters,
vmware.use.nexus.vswitch -
This would decide whether Nexus vSwitch in the VMware
cluster environment would be used/managed by CloudStack
for it's network infrastructure needs.
vmware.guest.network.vswitch.type -
This setting would enable CloudStack to use Nexus vSwitch
in the VMware cluster environment for guest traffic.
vmware.private.network.vswitch.type -
This setting would enable CloudStack to use Nexus vSwitch
in the VMware cluster environment for private traffic.
vmware.public.network.vswitch.type -
This setting would enable CloudStack to use Nexus vSwitch
in the VMware cluster environment for private traffic.

This fix will enable support for multiple NetScaler devices providing EIP service in same zone.
- Introduced global setting "eip.use.multiple.netscalers" to turn multiple netscaler support
- Enhanced configureNetscalerLoadBalancer API to take the PBR setup between the POD's subnet
and NetScaler device
- logic to pick a NetScaler (based on the guest IP and corresponding pod) while configuring INAT rule
