Currently doing some additional debugging on this, in the current state we're passing around the same pointer to a dictionary which is the same memory address. Therefore; the reference is being updated on all Host objects based on the last host to go through the for loop. Looking into doing some getter/setter instead to be more flexible.

Doing additional debugging it actually looks like the problem is something in this funciton. I've debugged for awhile and haven't been able to determine why yet.

            hosts[device.name] = _set_host(
                host_data=host["data"], name=host["name"], groups=host["groups"], host=host, defaults=defaults
            )

This is within the for loop, during the first iteration the connection options are correct, however once the second iteration happens it seemingly is updating a global variable which in return the initial loop iteration host now has been updated.(connection options) wise.
Trying to determine if there is a global reference that is being reused somewhere and since its overwritten its updating all hosts that have been previously processed.

want to say this was fixed with the implementation of the deepcopy in the inventory creation. #92
