KUTTL Apply

[kensipe]

Initially when added kuttl assert and kuttl errors it didn't seem too useful to have a kuttl apply since it is simply kubectl apply... however after working on a number of kuttl tests, it does seem useful. The apply phase of kuttl can have multiple files and can have multiple "commands" in a TestStep.

This task is to create a kuttl apply which will take a file and provide the apply for the series of object in the file. (or perform all aspects of a TestStep if defined).
