Alllow service to be disabled

[jdashton]

In some cases we may need to run this role against servers on which Apache httpd is disabled, or on which we want the initial state of the server to be disabled. This PR adds a variable that can be overridden when setting the enabled/disabled status of the Apache httpd service. The default value isenabled: yes, so there is no change to how this role has worked in the past. However, users can set this variable per host as needed.

Further, a pre_task can be used with code like the following to keep the current state of the service unchanged. This example assumes that the playbook changes the default values for both apache_state and apache_enabled, but demonstrates how to re-enable them if the service already existed on the box.

- name: Get service status on each host
  service_facts:
  tags: service_status

- set_fact:
    apache_state: "started"
  when:
    - "'httpd.service' in ansible_facts.services"
    - "'running' == ansible_facts.services['httpd.service'].state"
  tags: service_status

- set_fact:
    apache_enabled: "yes"
  when:
    - "'httpd.service' in ansible_facts.services"
    - "'enabled' == ansible_facts.services['httpd.service'].status"
  tags: service_status
