Original Issue: Fn::Map intrinsic function aws-cloudformation/cfn-language-discussion#41

Description

With the Fn::ForEach intrinsic function, you can iterate a given list to replicate a certain template snippet thereby avoiding repetitively writing a similar declaration for each object (e.g. Resource, Output, or Resource Properties) just like using a map function in many programming libraries.

Fn::ForEach traverses a single given List of Strings from first to last, and over each iteration, it references each item under a given template fragment to be replicated.
