Adding instance can't be done idempotently due to node_state

Bug Summary

When adding an execution node via the module the only node_state options are installed or deprovisioning, however if an instance is already installed the API gives returns state ready resulting in a false changed status

If state installed installed is passed to the module, it always returns state changed for an already installed instance.
Passing state ready is, however, not available because the module doesn't support it.
