Although Serverless supports timeseries, we have currently blacklisted all timeseries workloads in tenant migration/merge and split passthroughs using the requires_timeseries tag. As a result, there is no test coverage for the Serverless migration + timeseries combo. We should re-enable Serverless migration passthrough suites to support timeseries workloads. If this is not possible, the Serverless team would appreciate an explanation regarding:

1) Why enabling it is not feasible?
2) Whether it is possible to enable a subset of timeseries core tests or not?
