Expand sync iam target connections to make DTAP possible

Now that there is the option to save connections to target IAM databases/servers there is also the opportunity to introduce a proper DTAP environment. When setting up a target IAM you should have the option to select if this is a production/test/develop/acceptance environment. Each type should have it’s own set of options, for example:  

- Activate default system flows (you only want to do this on production in most cases). 
- Environment specific File storage locations.
- Deactivate certain tasks that are not allowed to run on test/acceptance.
