hiera('key',undef) Incompatible with future parser.

With puppet's furture parser enabled this module fails:

Evaluation Error: Error while evaluating a Function Call, Could not find data item cvmfs_timeout in any Hiera data file and no default supplied at /home/travis/build/cvmfs/puppet-cvmfs/spec/fixtures/modules/cvmfs/manifests/params.pp:40:29

These are the following contructs in the params.pp

$cvmfs_timeout          = hiera('cvmfs_timeout',undef)

These are all unnecessary now with hiera data bindings being the preferred way to use hiera.
Probably these should be deprecated.
