state[:password] not getting populated if Admin password is provided

[gcorpian]

I am working with a custom Windows AMI and since it is failing to get the admin password, I created a static password for the Administrator account and added it to the kitchen.yml instance.transport control. This results in the function fetch_windows_admin_password never getting called. Looking through the code, I can't see instances outside of that function where state[:password] gets populated. The problem this presents is that the line instance.transport.connection(state).wait_until_ready doesn't exit because no password was provided so it keeps waiting for the connection to be ready.

I see a few things needing to be done.

1. state[:password] should be populated when instance.transport[:password] is not nil.
2. A break should occur if instance.transport.connection(state).wait_until_ready exceeds a certain length of time.
3. A validation check put in place to ensure all required values are populated before requesting a connection.
