litmus cli as configmap creator & lambda function transformer

[AmitKumarDas]

Since end users will have their yaml git versioned & probably will have ksonnet instead of yamls. litmus cli should try to translate these files into yamls before creating config maps of them.
On a similar note lambda function should be translated with values before creating config map of these functions.

All of the above are pre-requisite before running the user story.

Similarly, these config maps should be deleted after running the user story.
