Improvement when CFN cannot create a resource

[Rmpanga]

Apologizes if this is created in the wrong repository.

Problem

When we use cloudformation to create a resource we notice 2 errors. The first error is a resource is missing a property

When that error is fixed we notice another error

Ideally we would like this error to be shown before the first one (or in conjunction to it) this way it will save developer time.
