add kubectl checks to limits:set tests

[bacongobbler]

As per

workflow-e2e/tests/limits_test.go

Line 10 in 003e0e6

// TODO (bacongobbler): inspect kubectl for limits being applied to manifest

, we need to add checks to kubernetes to validate that the correct limits have been applied to the deployed pods.

The tags_test.go now uses kubectl successfully--the only hitch was resetting $HOME to the original user so that the proper configuration is found. The kubectl code there provides an example that might be useful here.
