Datasource read needs to set an ID, then call resource read func
Add additional cluster attributes to datasource schema
* Generate datasource schema from resource
Datasource documentation also updated.
* add test for datasourceSchemaFromResourceSchema
* Code review changes
- Fetch Zone attribute any place where it *was* being fetched from the schema by
combination schema / provider-level attribute.
- Allow region to be unspecified if zone is specified.
- Switch one example to using provider-level zone as an example.
- Make provider-level zone optional. (Individual resources will fail if they can't find a zone.)
- Add tests for getZone and getRegion.
* Relax diff on maintenance_policy.daily_maintenance_window.start_time
If the maintenance window has been set outside of Terraform to a time with a
single-digit hour (such as 1:00), and the terraform definition is set to the
same hour but with a leading zero as per validation (i.e. 01:00), do not
consider the time to be changed (as we currently don't support update on this
property).
Fixes#719
* Generalise rfc3339TimeDiffSuppress and add more test cases
