US3.1: Ability to load configurations from github

[sukrit007]

As a developer, I need the ability for the totem to load the necessary configurations that are required to create a delivery pipeline for my application.

Acceptance Criteria

• Ability to load pipeline configuration from the GitHub repository branch.
• Ability to load pipeline configuration from the GitHub config repository if one does not exist in the application repository.
• Ability to load default pipeline configuration if one does not exist in repository branch or config repository.
• All loaded configuration should be added to Amazon S3

Note:

• Loading CodeSpec and deployment specification is outside the scope of current story
