Flow: While / Do While loop

As requested by Gus...

Ability to have a "Do While" loop in flow.

An alternative to this, which may be a better option, is a "While" loop. This is because a "Do While" loop will always run once whereas a "While" loop can run zero times and could therefore be a better option to provide users with greater flexibility.

Need to source some use cases and understand if the existing "For Each" loop can be used.
