As a module author, I'd like to be able to create a module that includes
a key_pair. I don't care about the name, I only know I don't want it to
collide with anything else in the account.
This allows my module to be used multiple times in the same account
without having to do anything funky like adding a user-specified unique
name parameter.
For now this only supports importing a key pair (by specifying a
public_key) property. In the future it'd be fairly trivial to support
key pair creation, with the private key returned as a computed property.
In real world usage you'd probably want to provide that public_key
property via a variable rather than hard-coding it into a terraform
config that'd end up in source control.
