What is the current behavior?

Issue Number: #743

What is the new behavior?

The agent role now properly moves hosts based on the checkmk_agent_folder variable.
Before, there were two possible behaviors. Either the host was in the expected folder and its atrributes were updated if set. Or the agent role would fail, if the host was in a different folder than defined in checkmk_agent_folder and had attributes set. While the new behavior now actually is idempotent, it might be surprising, that hosts would be moved in the folder structure,if the checkmk_agent_folder variable does not match the current folder of the host. So while this is a bug fix by definition, please take note and check your configuration!
