While the HEAD is pointed to the correct branch (might not exist), we created the initial files during repo creation still on the master branch (as it's an empty repo and clone by default sets up master when cloning an empty repo)
Adds the following:
- Add GetContent API (with gitrpc, proto, gitadapter changes)
- Add ListCommits API (with gitrpc, proto, gitadapter changes)
- DefaultBranch (to repo table in DB, update branch in git-repo, have default value in config)
* initial work on create repository
* create repository as single method call using client stream
* resources handler and files
* minor fix for wire dep graph
Preparing the support for harness specific API router + http handler, which allows us to have complete control over the rest api naming and functionality, without having to do complex path rewrites or request / reponse rewrites inline.
