Publish a Module

This endpoint creates a Module from a VCS repository.

The module's source code directory should follow the
standard module structure.

Scalr extracts various meta information from the module's source:

• It's important to provide each variable and output blocks with a meaningful descriptions, as they
  will be displayed in a Module and Workspace Variables pages for your internal users.
• README or README.md file will be displayed on a Module page.
• Nested modules from modules/ directory will be searchable and available though the Registry just
  like top-level modules.

Modules can be published on both account and environment scopes.
If neither scope is specified in the request body, the module will be published in the
same scope that the related vcs-provider is published.
