Removed unrequired files. Reworked parameters
Cloverleaf role for simple preparation
SELinux role, the usual stuff to disable it but in a role that can be required as a dependency
Firewall role, the usual 'disable it', but as a role to require it in dependencies
Added an export to prevent ansible's ssh known host prompt
Renamed oracle role to oracle_database to fit with incoming oracle_client. Removed selinux and firewall in favor of dependencies to those news roles.
Added galaxy_info
Improvement of inventory file. Added some wires for new cloverleaf roles and stuff
Small changes due to reorganisation
Created a oracle_client role for instantclient installation, thus reorganized everything involved
