Permutations, divide PC tests into two caegories

Divide CP tests into two caegories
1. Independant
2. chained

### Independant
Can be permutated.

### Chaned
In chaned start by a list of steps that have a logical chain, and put them in the chaned group.

Start by locating the CP tests in the repository and review how their steps are currently organized. Separate tests into independent and chained groups, with permutation applying only to independent tests; done means both categories are identifiable and the chained steps retain their logical order.
