Add kernel tuning role

This new role will add, load, and modify kernel tuning
options as well as load kernel modules. This role provides
an interface to allow users to customize the kernel
parameters and modules as needed.

Test Matrix:
  - default - Runs through the role top to bottom with all default
              settings
  - extra - uses the available interfaces to customize the deployment.
