Create separate users for helm test

Currently each service uses the same name for their helm test user,
"test". While this works when services are ran sequentially, when
multiple services are deployed and tested at the same time, it can
lead to a race condition where one service deletes the user before
the other is done testing, causing a failure.

This change makes it so that each service defines its own test user
in the form of [service]-test.
