cloudposse/terraform-null-label

### [`v0.22.1`](https://togithub.com/cloudposse/terraform-null-label/releases/0.22.1) [Compare Source](https://togithub.com/cloudposse/terraform-null-label/compare/0.22.0...0.22.1)

Add var.attributes to end of context.attributes, not vice versa @​Nuru (#​114)

#### what - Add `var.attributes` to end of `context.attributes`, not vice versa - Update to current workflows (with some exceptions) #### why - Modules should append to attributes passed in, not insert themselves ahead of others - New features, like auto-format (but holding back some, because this is a special module) #### references - closes #​113 - closes #​108
