CloudStack Terraform Provider - Add datasources for the existing resources

CloudStack has recently made the first release of its own terraform provider, called CloudStack-Terraform Provider v0.4.0 and as of today it supports 25 resource types, and 1 Data Source type. I would like to extend the list of data sources supported by the CloudStack Terraform provider and implement data sources for the existing cloudstack resources. To solve this issue, I will implement data sources for all the resources already supported via the Terraform CloudStack provider and possibly extend that list of supported resources and data sources to other major CloudStack resources which are not available yet.
