Make Prometheus daemon restart/reload with sudo privileges.

[swesterveld]

I'm trying to include the cloudalchemy.prometheus role from our own monitoring role like this:

- name: Install Prometheus Server
  become: yes
  when: act_as_prometheus_server == true

  include_role:
    name: cloudalchemy.prometheus
  vars:
  [...]

This results in a fatal error, at the point when running the handler that should restart prometheus:

RUNNING HANDLER [cloudalchemy.prometheus : restart prometheus] **********************************************************************************************************************
fatal: [monitor]: FAILED! => {"changed": false, "msg": "failure 1 during daemon-reload: Failed to execute operation: Interactive authentication required.\n"}

The service could only be restarted with sudo-privileges, which in the case of an include_role or import_role won't get picked up correctly by the handler responsible for the service-restart/-reload.
This PR will make sure that the prometheus.service will be restarted with the correct privileges.
