MongoDB installation Updates (see below):

 - Explicitly define the mongodb upstart init conf path
 - Mongodb repo updates for 3.4
 - Allow tuning of mongodb service name
   - New vars:
     - `rocket_chat_mongodb_service_name`: mongod (string)
     - `rocket_chat_mongodb_org_pkgs`: false (bool)
     - `rocket_chat_mongodb_org_version`: 3.4 (string)
- Implement suggestions from RocketChat#40 RocketChat#50
  - Allow fine-grained tuning of `MONGO_URL` inside service files
  - Configure `rocket_chat_mongodb_URI` with jinja2 logic
    - New vars:
      - `rocket_chat_mongodb_user`: ~ (string)
      - `rocket_chat_mongodb_password`: ~ (string)
      - `rocket_chat_mongodb_database`: rocketchat (string)
      - `rocket_chat_mongodb_use_tls`: false (bool)
      - `rocket_chat_mongodb_URI`: computed result
- Move replSet task into mongodb.yml
- Change idempotency of replSet command
  - Now actually check on the JSON output of the
- Add MongoDB.org offical package install task for RHEL
- Vaariabilize `rocket_chat_mongodb_config` for debian packages
     - Set the variable explicitly in the org packages task to match the
       official location
- Fixes: RocketChat#40 RocketChat#50 RocketChat#54 RocketChat#71

Mongodb changes from @photoninger (Thanks also for RocketChat#71 as a reference!)

 - Add mongodb_service_name to README
 - Variablize mongodb log to match service name

Fixes: RocketChat#71
