Determine Measurement Limit for new Data Explorer

## Spike Description

In the old data explorer, there was a hard limit of 200 or 500 entries in the measurement list, depending on a feature flag setting.

We can assume this was done because of performance and the impact of gathering a large list and all the associated metadata.

With the performance improvements that have been made in both back-end and front-end and with the different way we are handing metaqueries, we should determine if this limit is still necessary, and if so - what limit is feasible.

It certainly *seems* like we could show more than 200 entries without it being problematic.

This spike is for doing some testing and analysis to determine what our options might be here.

## Deliverable

- Recommendation on what (if any) limit can be put on the measurement list in the new data explorer
