Make puppet-tripleo compatible with latest puppet-rabbitmq

https://review.opendev.org/#/c/677082/ merged today and moved puppet-rabbitmq to 9.1.0
which is breaking our spec tests:

https://zuul.opendev.org/t/openstack/build/e767db93fe214514bebc065a64288548/log/job-output.txt

So we error out with things like:
2019-08-19 07:19:37.527187 | centos-7 | 1) tripleo::certmonger::rabbitmq on redhat-7-x86_64 behaves like tripleo::certmonger::rabbitmq should include the base for using certmonger
2019-08-19 07:19:37.527435 | centos-7 | Failure/Error: include ::rabbitmq::params
2019-08-19 07:19:37.527713 | centos-7 | Puppet::PreformattedError:
2019-08-19 07:19:37.528769 | centos-7 | Evaluation Error: Error while evaluating a Function Call, Could not find class ::rabbitmq::params for centos-7-rax-ord-0010255916 (file: /home/zuul/workspace/spec/fixtures/modules/tripleo/manifests/certmonger/rabbitmq.pp, line: 51, column: 3) on node centos-7-rax-ord-0010255916

Let's remove any reference to rabbitmq::params and also the following
two notifies:
  File[$service_certificate] ~> Service<| title == $::rabbitmq::service_name |>
  File[$service_key] ~> Service<| title == $::rabbitmq::service_name |>

They do nothing in a containerized deployment anyway.

Tested as follows:
- Full downstream OSP15 HA deploy
