Added tasks to copy the app and ossec alert gpg key public keys to the remote host since production will not be using vagrant

Removed the word 'path' from the the variable names for the app/ossec gpg key and the custom header image variables since it does not a path anymore.

The custom header image, app gpg public key, ossec gpg public key and the smtp's CA cert need to be either in the install_files/ansible-base directory or the respective role's file directory
Added a unique test gpg keypair since in production these would also be two separate keypairs.

The application's gpg private key is airgapped, while the admin's gpg private key is on their networked work machine so they are able to decrypt the emails.
GPG is being used for the OSSEC alerts to protect them in the event that the organization email server is compromised.
