DataFactory API returns resource group name in lower-case

[mbfrahry]

Hello! This is following up on #3964. It looks like the DataFactory API based off 2018-06-01 inside v26.7.0 of the azure sdk also returns the resource group name in lower case.

Terraform is throwing a ForceNew when a capitalized resource group name is passed into any DataFactory resource. For example:

------- Stdout: -------
=== RUN   TestAccAzureRMDataFactoryDatasetPostgreSQL_update
=== PAUSE TestAccAzureRMDataFactoryDatasetPostgreSQL_update
=== CONT  TestAccAzureRMDataFactoryDatasetPostgreSQL_update

@LijuanZ Could you please have a look at this?

This is by design that Data Factory stores only lowercase resource group name
