Running these services as daemons so that we can take advantage of Travis' container-based infrastructure. One test had to be updated, most likely due to sorting not behaving as expected. All tests will be updated in the future to properly prepare test data, and not rely on sorting/querying.

Infrastructure Cleanup (Part 2)

Infrastructure Cleanup (Part 1)

- Updated title to mention the common name for this service (forums)
- Moved notes about devstack closer to top of development section.
- Noted default values for Elasticsearch and MongoDB servers
- Added Travis build status

This change allows support for other Ruby mangers (e.g. rbenv) in addition to RVM.

Updating bundler on Travis

The bundler version on Travis is outdated and has issues installing the gems. Updating to latest version.

Update Mongoid to 5.x release (mongodb 3.x + compatibility)

MA-1742; return read status on GET thread for user_id provided

MA-1190; Thread PUT -  update thread read status

MA-1189 ThreadGET - optionally include response comments via 'recursive' bool

changed timeout to 6 seconds

ThreadAPI: returned resp_total for existing question and new thread

Added last_activity_at index

Use bulk operation instead.

The bulk operation should be faster and more performant than doing the db.find.update
