(PDB-905) Fix containment-path for skipped events

We had removed some < v4 reporting code as part of the last release, but I had
also accidentally removed containment-path for skipped events. This was an
effort to drop older Puppet support basically.

This patch fixes that problem, and fixes the tests.

I've also cleaned up a couple of other typos and style items, plus
removed one more case of < v4 report format checking.

Fix the dependency for puppet for the PuppetDB package for the correct version

We had accidentally reverted the parameterized handling around the Puppet
dependency in our Debian package control file. This patch corrects that.

Use c3.large instead of c1.medium

This corrects all the configuration for beaker to use c3.large as we did for
stable.

(PDB-882) Setup basic facts performance testing

This introduces our first pass at performance testing, in particular we have
targetted loading structured facts.

The benchmark tool is now capable of using a series of provided fact JSON files,
so we can use that tool for this purpose. We've also provided a set of basic
seed files for these tests.

The tooling: `rake test:beaker` has now become `rake beaker:acceptance` and
performance tests are started using `rake beaker:performance` instead.

The testing introduces a new host configuration specific to this work, in particular
we are using a single c3.xlarge instance. This is isolated from the acceptance testing
one so we can tune this on its own.

This also fixs a number of side issues:

* benchmark -h was broken, now fixed
* The -rp switch no longer worked, this has no become -r
* Some of the client based stuff was strewn around our code base, its now
  centralized in puppetlabs.puppetdb.client

(PDB-489) return producer timestamp

This exposes our "producer-timestamp" field on the factsets and catalogs
endpoints.  On factsets the field is queryable and orderable. The next step
will be to push the generation of this field back to the agent.
