Windows Admin password should get polled automatically

[gmiranda23]

It takes about 4 mins for the windows admin password to be available on new windows instances. These should get automatically polled somehow and be made available in the portal view.

There don't seem to be good approaches to this that are documented. These may provide some leads:

aws/aws-sdk-ruby#459

Chef::Provisioning::AwsDriver.wait_for_admin_password(machine_spec) seems to do this.

Otherwise, the logic for in-browser RDP & SSH exists and is validated. Closing #4 in favor of this issue.
