Loop enhancements: x times loop & introduce variables

[ahmad-swanblocks]

Is your feature request related to a problem? Please describe.
In many cases, I need to run a loop of x times and for every iteration I execute an action and I need to compare the result of the action with the result of the previous iteration.

Basically, I have two limitations:

1. I cannot run a loop of x times unless I have a list of x items
2. I cannot save the result of the current iteration to compare it with the next one

Describe the solution you'd like

1. Allow to configure a loop with x times and no need to run on a list
2. Introduce variables to store the iteration result
