In some cases we want to pass on information to other apps to allow
them to infer who or what is performing requests against a website.
For now we're exposing an empty object, but we hope to extend the
object with meta data that will be useful for other apps that have been
instrumented on the website.

This test will evaluate and return the value. It should be an empty
object and not null.

We're renaming this since this file will embed scripts other than
web vital scripts.

To be consistent with how we work with other injected scripts, the k6
object is being moved to its own js file. This also helps us avoid
working with globals.

It's worth noting that the k6 object will need to be mutable at some
stage to add test specific unique metadata in the future.

This commit now works with the new k6 object file instead of the global
k6 object file.
