Summary

support for azure devops git repo for application code

Motivation

many organisation are using azure devops git repo as provider. we need to build support for them.

Proposal

1. remove .git suffix validation for git material
2. perform git related network call (pull, clone, fetch) via cli instead for go-git(azure repo not supported by go-git ref: Git Clone does not work with Azure DevOps repos go-git/go-git#64)
