initial vendordata support

This adds the ability for a datasource to provide "vendordata".
The difference here is that vendordata is from the vendor (cloud provider)
where user-data is from the user.  By enabling this channel, the vendor
can have input on how the instance is set up without modifying or needing
to understand the user-data.

vendordata is generally consumed exactly like user-data, but the user
has the ability to disable its consumption.

The only datasource supporting this at the moment is SmartOS.
