Read encoded with base64 user data

This allows users of CloudSigma's VM to encode their user data with base64.
In order to do that thet have to add the ``cloudinit-user-data`` field to
the ``base64_fields``. The latter is a comma-separated field with
all the meta fields whit base64 encoded values.
