changes to behavior on specifying keys.

The most likely end user operation (or at least a valid one) for base64
encoding would be to encode the user-data, but leave all other values
as plaintext.

In order to facilitate that, the user can simply add:
 b64-user-data=true
to indicate that user-data is base64 encoded.

Other changes here are to change the cloud-config and metadata keynames
that are used.
  base64_all = boolean(True)
  base64_keys = [list, of, keys]

Fixed up tests to accomodate.
