v1.0.0 Initial release with production Semantic Versioning

Initial release with production Semantic Versioning, part of Cloud Posse's general policy to convert to production versioning as we make updates to relatively mature modules.

This version is functionally equivalent to v0.4.3. The only differences are to the support framework (for things like developing and testing the module).

git.io->cloudposse.tools update and test framework update @dylanbannon (#32)

what and why

Change all references to git.io/build-harness into cloudposse.tools/build-harness, since git.io redirects will stop working on April 29th, 2022.

References

• DEV-143

Rename the exported `security-group-inputs` file to `security-group-variables` @aknysh (#31)

what

• Rename the exported security-group-inputs.tf file to security-group-variables.tf

why

• Standardize on file names with variables for specific resources.
  For example, we have spotinst-variables.tf for Spot, security-group-variables.tf for SG, etc.
