cloudprovider/cloudstack: Fix a bug where we assume IP addresses instead of a hostnames
Because of how our test environment was setup, we didn’t notice that we were assuming the load balancer hosts list to always be IP addresses, while they actually are hostnames.
So without this PR, the load balancer code will not work as expected as it will not be able to find the nodes that need to be load balanced.
Also updated some comments and added a check to prevent trying to release a public IP if we don’t have one.

This commit adds logic for allocating and associating a public IP, if the `—load-balancer-ip` option is not used. It will do proper management of IP’s that are allocated by this provider, so IP’s that are no longer needed/used will also be released again.
Additionally the provider can now also work with CloudStack projects and advanced (VPC) networks.
Lastly the Zone interface now returns an actual zone (supplied by the cloud config), a few logical errors are fixed and the first few tests are added.
All the functionality is extensively tested against both basic and advanced (VPC) networks.
