Add one-time randomization support for FieldTrial, and the ability to
disable field trials. I am going to have a need for both soon.
Cleaning up some comments about empty trial names, adding static
method TrialExists() and simplifying many call sites by using this
method.
While I'm in there and needing base/OWNERS approval, add an OWNERS
file for base/metrics that adds jar@chromium.org as an owner for that
directory.
