bumps up the default retry time.

retry: add retry package for retriable tests 
The current retry framework in testutil/testprc.WaitForResult uses
a func() (bool, error) callback until it succeeds or times out.
It captures the last error and returns it.

    if err := testutil.WaitForResult(t, func() (bool, error) {
	if err := foo(); err != nil {
	    return false, err
	}
	...
	return true, nil
    }); err != nil {
	t.Fatal(err)
    }

This makes the test functions more complex than they need to be since
both the boolean and the error indicate a success or a failure.

The retry.Run framework uses a an approach similar to t.Run()
from the testing framework.

    retry.Run(t, func(r *retry.R) {
	if err := foo(); err != nil {
	    r.Fatal(err)
	}
    })

The behavior of the Run function is configurable so that different
timeouts can be used for different tests.
