An aggregate score is one derived from multiple problems (such as the
cumulative score for a vertical element containing many problems). Sending
aggregate scores immediately introduces two issues: one is a race condition
between the view method and the Celery task where the updated score may not
yet be visible to the database if the view has not yet returned (and committed
its transaction). The other is that the student is likely to receive a stream
of notifications as the score is updated with every problem. Waiting a
reasonable period of time allows the view transaction to end, and allows us to
collapse multiple score updates into a single message.

The time value is in seconds.

Separate installing datadog and new relic on sanboxes

Whitelist the lti_provider endpoint

This uses OAuth1 and configured tokens and shouldn't use basic auth.

Rename playbook for ad-hoc reporting box management

Though the name "tools-gp" is now a misnomer, a new on-call devops would
probably know the place where read-replica scripts live by that name.
Therefore, until the server is renamed, the playbook should match it.

Feanil/update sandbox workers

Be able to update workers.

Before this change, you couldn't actually update workers because their config never got updated and they never got restarted when you updated the edx-platform.  This will allow us to quickly update the workers.  We can't do this as part of the edxapp.yml play because that is used in multiple places.

OPS-976: Remove serial option from mongo play

The mongo play doesn't work when run serially. It's run non-serially in
other places (vagrant-cluster.yml, for example). The serial option seems
to have been added mistakenly in 2632cb86 (#1522) and not tested.
