added a validate role that would only be run when running non-staging or...

... development playbooks.

This role verifies that the development/testing gpg keys, ossec alert email address, and sasl credentials are not used for production
running this role would require just require that the values did not equal the pre-defined staging values. It will not error out if the values are undefined. (if that is what you are asking?) We can/should add that though
