basic support for initialization parameters

I added a new type that allows you to manage initialization parameters through puppet. You'd use it like this:

        init_param{memory_target:
                value   => '0',
        }

        init_param{control_file_record_keep_time:
                value   => '42',
        }

        init_param{audit_trail:
                value   => 'NONE',
        }
`end` at 33, 5 is not aligned with `it 'should pick its value from element NAME' do` at 30, 1<br>Tab detected.
