Add .deb support to puppet-opendaylight

Add .deb support to puppet-opendaylight

This patch adds .deb support to puppet-odl. It adds beaker tests for Ubuntu 16.04.

This removes the tarball install method logic for both RedHat and Debian based OSs.
It adds logic that looks at the OS and decides the install repo: `rpm_repo` or `deb_repo`.
Addtionally, this patch adds `lsbdist`* facts for Ubuntu tests.

This also updates the README.md to reflect these changes.
