Adds ability to populate SSH Banner text

A puppet manifest to allow the toggle of 'Banner' in sshd_config
and enable population of an SSH login banner needed for security
compliance such as DISA STIG

If `Bannertext` is set as a parameter, the `Banner` key within
sshd_config is toggled to `/etc/issue` and the content is copied
into the `/etc/issue` file
