[New Feature]: create repository in github from template repository

[Paul Williams]

Is your feature request related to a problem? Please describe.
Currently the app-generator creates the scaffolded code in generated directory locally. It would be nice if this is in source control management like GitHub.

Describe the solution you'd like

• Step 1: Create a new repository from devs-from-matrix/basic-template-repository
• Step 2: Generate\scaffold code (this is already taken care)
• Step 3: Initialize the generated code to the new repository and commit and push the changes. You may require a token hence pass it as an argument to the gulp task

Additional context
The token passed as an argument is a temporary solution. We need to me use of GitHub App
