Added karma threshold reporting & failure

This patch adds unit test coverage threshold reporting, adding
statement, branch, function, and line coverage to the console
output in infra, and failing the build if the threshold has not
been met.

The threshold values have been set to the current observed
coverage values - future patches should update this up as
coverage improves.
