Fix beaker on xenial

Since the beaker jobs are being run on xenial, we need a special nodeset
for it, otherwise beaker gives an error:

 beaker-hostgenerator was not able to use this value as input.
 Exiting with an Error.

We also want to install puppet from the Ubuntu repos rather than from
puppetlabs, since puppetlabs doesn't support puppet 3 for Xenial. For
centos we can keep the install process the same.

Additionally, this patch updates params.pp to distinguish between JRE
packages based on the Ubuntu release so that these module will work on
Xenial. We still keep support for trusty.

Finally, remove spec assertions that are not useful, including
verifications that packages are installed and config files existing. It
is enough to assume that if the puppet ran without errors that it was
able to also successfully find and install packages and lay down config
files. We remove these tests instead of updating the package check for
the new JRE package.
