One common frustration of end users running the e2e suite is that
they take a significant amount of time and it is difficult to
gauge progress.
Even if tailing the logs it can be difficult to see where one
test starts and another ends or understand the if there have been
failures in the past 1h of logs.
This change adds a new custom reporter which prints summary information
as tests complete. This includes the number of tests to run and how
many have been passed/failed/skipped along with which tests have failed.
A new flag can be set which pushes these values to an endpoint. This is
intended for integration with Sonobuoy but any endpoint could consume and
surface this data to the user so they can better understand the state
of the current test run.
