Sonobuoy v0.16.1

Sonobuoy v0.16.1 mitigates a major bug found in the upstream E2E conformance image. Users are highly encouraged to update. See #910 for more details.

What's new

Golang-based test runner for Kubernetes 1.16.0+ clusters.

Within the test image used for end-to-end tests are some wrappers which invoke those tests. Historically those were written in bash but various problems have occurred which caused us to add a Golang-based runner. The benefits of this are:

• avoids a major problem where 1.16.0 clusters with the bash runner would not report test results properly when there are failures
• improved error handling and logging
• ability to further customize the test run by allowing arbitrary flags to be passed via the env vars. This means that many more testing options are supported including provider specific settings that were previously unsettable.

What's better

• sonobuoy results will print results for all plugins by default. This way you don't have to remember which plugins were run or how their names are exactly spelled to figure out what is inside a tarball.
• sonobuoy gen plugin added a --format flag which allows you to specify the result format.
