Previously the `/api/2.0/groups/create` threw a `RESOURCE_ALREADY_EXISTS` if the group was already present (as per [docs](https://docs.databricks.com/dev-tools/api/latest/groups.html#create:~:text=This%20call%20returns%20an%20error%20RESOURCE_ALREADY_EXISTS%20if%20a%20group%20with%20the%20given%20name%20already%20exists.)). However, we now get ``` $databricks --profile DEV groups create --group-name 'testgroup1' { "group_name": "testgroup1"...
