Conditional Iteration Construct/Action in Microflows/Nanoflows (For/While loops)

Currently we have a loop action (or iterator) over lists. A similar one which iterates until a condition is met is also nice to have. This would help create for and while loops which is a very common case when implementing business logic.

I know it can be achieved using variables, split and merge actions but having an iterator like action would make the flows more readable and maintainable.  Also, a little more low-code when you don't have to create the variables and split actions every time? 

Some simple use cases that we keep coming across every now and then:

• Do something n number of times
• Do something till value of variable x is less than a constant value
• Do something indefinitely till a variable has a specific value
