Rohit Yadav ca99603321 server: NPE checks and improved case checking
- pool allocation checks for both root and data disks
- NPE checks to not add null object in collection or try to migrate null VM
- HA work tries need to increment and be given up when max retries are crossed
- VM creation should check IP address format for IPv4 and IPv6
- If userdata is not supported by a network, then fail early if userdata, ssh key,
  or password enabled template is passed/used
