Subject: Introduce queue client "plugin" namespace and interface, with a Stomp
 client implementation.

Puppet::Util::Queue provides queue client mix-in behaviors that enable easy queue client management for consumer classes.  Some relevant behaviors include:
* standard Puppet instance loader behavior for loading queue client modules on-demand based on the client module specified by symbolic name
* singleton registry of known queue client types (based on symbol-to-class mappings from the instance loading behavior)
* simple interface for working with an actual queue client instance

Puppet::Util::Queue::Stomp wraps the Stomp::Client class to provide an initial queue client option supporting the Stomp messaging protocol.  This defines the interface for all Puppet queue client plugins going forward.
