The region var seems to be ready to be deprecated

[nnsense]

Describe the Bug

Not really a bug, but the region variable is apparently unused, see our discussion on slack, but leaving it default = null might lead tools like terragrunt to force the user to set it anyway.

Expected Behavior

It is not used, but it still requires to be set. Without it, we can get rid of an unnecessary input.

Steps to Reproduce

Leave the region variable unset.

The problem is that removing it would break all existing uses that are setting it. It will have to wait until the next major release to be removed.
