Ability to import data into WPT from a file

[Nooshu]

Feature Request Summary

It is possible to export run data from a test at the moment as JSON / HAR etc, but maybe a long term function could be the ability to pull this data back in?

What's the motivation or use case for the change/feature?

I have lots of tests that were run, and I've blogged about the waterfalls, but if I were to have to recreate them it would be almost impossible. I'd loved to have been able to download and store the run data in a file and given users the ability to "see this waterfall for yourself" e.g. a user clicks on a link, if the data is stored in the cloud, WPT would "pull in" the data and recreate the test run allowing a user to look over the real test the waterfall came from.

I realise it all sounds so easy when typed out, but I bet it isn't! More than happy to discuss further for clarification if required.
