Arvados

Every page load as well as dashboard refresh at 15s intervals results in computing user notifications ( @@notification_tests ).

This is especially expensive in su92l, but not too cheap in qr1hi either (see log below).

It would be desirable that we remember the fact that the user has created a pipeline_instance and a collection in user properties (similar to getting_started notification) and use this information instead rather than computing this for every page load / refresh.

We might be able to accomplish this by setting these properties the first time they are found when computing @@notification_tests (rather than overloading server side when these objects are created).
