Remove dependency on reduction code

[Gesner Passos]

Remove the dependency, by moving the code that is inside reduction folder to SANS folder. This one will create files even bigger inside SANS right now. It is not ideal, but, changing here means that we could eventually break users scripts.

re #9014: Bring reduction steps to sans_reduction_steps

While moving, I've tried to remove those methods and attributes that we were not using at all. It might have more, which must be investigated in another opportunity.

re #9014 Improve usage of mantidplot when not in GUI mode

While testing the changes, I've seen that we were silently ignoring exception when trying to use mantidplot in script mode. It is better to check if it is available and use only when it is.

re #9014. Improve the solution for long log

The changes here were introduced in #8949, but while testing the changes through the systemtests I reckognise that some times it may return a single value. Hence, here it tests first if there are more than one value before selecting the last one.

re #9014. Ensure assumption of receiving workspace reference

While checking this ticket I found that some system tests were passing string to this method and were 'silently' being ignored. This, fixes it.

re #9014: Move the reducer_singleton to scripts folder

This is to allow Indirect to use the same module. And because it is not strictly related to SANS.

re #9014: Move ReductionStep to reducer_singleton module

After discussion, this allows Indirect to use all they need to implement #9093.

Tester:

This ticket was mainly getting from reduction folder what we are already using for the SANS reduction. Everything should be working as before. The systemtests are telling that we have all running, and our GUI do not write any code using that folder directly (Well, we have to wait till Friday to be sure, last commit was on Thursday).

Hence, code review is the main point here.
