Add attribute for overriding lsb codename in apt repo configuration

cwjohnston commented 7 years ago

Description

Adds an attribute for overriding the "codename" automatically detected by Ohai. This attribute allows the use of Sensu packages built for Ubuntu LTS releases to be used on non-LTS releases, e.g. xenial packages can be installed on wily and yakkety systems.

Also upgrades ChefSpec from ~> 4.0 to ~> 6.0, as was expedient to fix a bug with regard to add_apt_repository assertions.

Motivation and Context

Solves problem described in https://github.com/sensu/sensu-omnibus/issues/162

How Has This Been Tested?

Added unit tests, tested functionality in local test-kitchen with a yakkety (16.10) VM.
