Inconsistent uuid generation in azure_arm

[foospidy]

Summary

Azure returns inconsistent casing of the resource groups name in the id string, resulting in different uuid's for the same node (depending on what calls you make).

Detailed Information

When a node is created, the resource groups name in the id string is lower case. In subsequent calls, like in list_nodes(), for some reason Azure returns the resource groups name in upper case. This results in a different uuid from when create_node() is called. This also breaks wait_until_running(). Forcing the id string to lower case in _to_node() seems to resolve this issue.

I made the change here: foospidy@2682d12
