Make this an integer value and of type Stdlib::Port

[treydock]

This should be of type Stdlib::Host

I would recommend adding an acceptance test so that in this context, https://github.com/treydock/puppet-module-keycloak/blob/master/spec/acceptance/1_class_spec.rb#L131 , change to set syslog => true and then maybe add another context after that one where the class definition is this:

      include mysql::server
      class { 'keycloak':
        datasource_driver => 'mysql',
      }

And call it like "reset back to defaults" or something.

So far looks like only remaining issues are data types used for syslog_hostname and syslog_port.
