community: remove integration as the product has changed (#159)

This code dates back to when [Tigris Data][1] was a database as a
service. That product has since been sunset and the current product is
globally distributed object storage.

Removing this code as there is no possible way for it to work.

I am running into a problem with the removal though, when I run tests
locally I get an error that the tigris import doesn't exist:

```

```

Where is this coming from so I can fix it?
