Add new object type for Duo integrations

A new object type, duo (Wallet::Object::Duo), is now supported.  This
creates an integration with the Duo Security cloud multifactor
authentication service and allows retrieval of the integration key,
secret key, and admin hostname.  Currently, only UNIX integration
types are supported.  The Net::Duo Perl module is required to use this
object type.  New configuration settings are required as well; see
Wallet::Config for more information.  To enable this object type for
an existing wallet database, use wallet-admin to register the new
object.
