/**

* The users of a run: the manifest `create_load_test_sessions` writes
|
|
* (src/backend/loadtest), one session per virtual user.
|
|
*
|
|
* k6 reads the file once, in the init context, and every VU keeps the session
|
|
* of its rank: with more VUs than sessions a user is logged in several times,
|
|
* and the API throttles per user (80/min on documents) — ask for at least as
|
|
* many sessions as VUs.
