In an attempt to make it easier to
1) navigate the integration test output,
2) find the cause of test failures, and
3) run individual tests, make it easier to run individual
integration tests from the command line,
...this change ports some of the OSS integration tests away from
GoCheck and implements them in terms of the standard `testing`
package.
The main changes are:
* Test suites are now constructed as a normal Test function
with many subtests.
* The GoCheck assertions have been replaced with equivalent
assertions from `testify/require`, for example:
`c.Assert(err, check.IsNil)`
becomes
`require.NoError(t, err)`
... and so on
