CLOUDSTACK-4709: UI > template > register template > when zone dropdown is selected as All Zones, show all hypervisors supported in cloudstack instead of only hypervisors available in all zones.
Fixed sysvmadm helper script (responsible for restarting/recreating VRs when needed on upgraded setups due to template changes) to have -v option. When -v is specified, all VPCs in the system will get restarted. As a part of the restart, VPC routers will get recreated
