Update stdlib module to latest 4.x

The latest verion 4.1.0 stdlib module has some new functions added
that are useful. Specficially, the delete_undef_values function had

Neutron Nova Interactions Support

Recent versions of Neutron are able to provide active notifications to
Nova about changes to port status and data.  This change adds the
neutron::server::notifications class to allow Puppet to configure
this feature when setting up a Neutron server.

neutron.conf requires a tenant UUID for communicating with Nova.
This changes adds adds a custom type and provider to translate an admin
tenant name to the required UUID.
bump head to support for managing ssh keys

This change permits provisioning ssh public and private keys as part
of creating the "nova" user.  There are no changes to the default
behavior
    of the module.  This changes introduces three new parameters:

    - nova_public_key
    - nova_private_key
    - nova_shell

    These changes are intended to permit configuring live migration via
    qemu+ssh connections to remote hypervisors.

this includes the commit that: Move libvirt options into a group

There are a bunch of libvirt specific flags which are currently in
the default group. This is confusing to users of other hypervisors, and
poor hygiene. We should move these options into a group of their own.
