To clone Git repositories, we need a key, but when provisioning a new server, if we generate a new key, it won't be available on Git repositories hosting like GitHub.
So, currently, deployment fails like this:
----------
          ID: /var/51-wwwroot/api
    Function: git.latest
        Name: ssh://vcs@devcentral.nasqueron.org:5022/source/api.git
      Result: False
     Comment: Failed to check remote refs: Host key verification failed.
              fatal: Could not read from remote repository.
              Please make sure you have the correct access rights
              and the repository exists.

     Changes:Perhaps a master key would be more pertinent, if so, that's a candidate for Vault.
