smear just a little bit of minimal DSL wiring into the Chef::Report
class so that classes can wire themselves up automatically as
handlers.

this also extends the Chef::Config[*_handler] arrays to take classes
as well as instances.

in the case of passing a class that is not a singleton, a new instance
will be created when the report is run.  it will obviously be difficult
to pass any state into this instance.

if the class that is passed supports calling `#instance` we assume it
is a Singleton and get the instance and use that.  this is to support
other chef code grabbing/creating the singleton instance and poking
it with data (probably configuring where the reporter goes and what
creds it needs to publish and other stuff).

This is an entirely mechanically generated (chefstyle -a) change, to go
along with chef/chefstyle#5 . We should pick something and use it
consistently, and my opinion is that double quotes are the appropriate
thing.
