Data completeness dashboard

[ryscheng]

Describe the feature you'd like to request

Would be nice to have a status page on the web app that allows us to easily visualize what data is missing

Describe the solution you'd like

I think we can just visualize the event pointer table, looking for artifacts where the end date is older than a certain buffer from the current date.

Open question - how do we know if a start date is insufficiently early? CC @ravenac95

Describe alternatives you've considered

TBD

Can we just put this in the project page so people can clearly see what data is missing?

[ravenac95]

I'm leaving this here but it's possible that with the tools we are intending on using, dagster/airbyte we may already get a UI to see the status of all data ingestion.

When was this added to sprint 65?

[ryscheng]

Looks like we're on track to using Dagster for this purpose once we get some public instances running in our k8s cluster

[ryscheng]

Lets repurpose this as populating metadata in MaterializedResult for all assets
