playground/builder: use keymanager instead of on-disk credentials

Needed in order to be able to safely share the principal among several
processes.  With the change to lock credentials loaded from disk as part
of v.io/i/1214, sharing on-disk credentials among processes without
using an agent will be disallowed.
