Load Wizards from AWS Shell data path

[joguSD]

This is to get the wizards I've created checked in somewhere and begin the conversation of how wizard models should be integrated with the shell. From previous discussion it seems that each service should have a wizards-1.json file that has a key corresponding to each of these wizards. With this approach the wizard handler command would likely change from .wizard <name> to .wizard <service> <name>. This would also likely impact the specification for wizard delegation in a similar manner in that the service would also need to be specified. Perhaps rather than the resource being the wizard name directly it would look more like:

"Resource": {
    "Service": "ec2",
    "Name": "WizardName"
}
