Lifecycle for BeforeEach and AfterEach

[kensipe]

Add ability to have before each and after each conditions defined in TestSuite to be applied / asserted before and after each test

[kensipe]

likely want a series of things for a "BeforeEach"

1. command
2. manifest (apply/delete)
3. assert
4. error

It looks like it a before and after step prepended and appended to existing test steps
