for example, assuming the current content of host.yml is:

github.com:

    users:

        user1:

            oauth_token: gho_XXX

        user2:

            oauth_token: ghp_YYY

    git_protocol: ssh

    user: user1

    oauth_token: gho_XXX

when I run:

gh repo create user2/hello --public --source=. --remote=origin

it will get the same effect as:

gh auth switch --user user2

gh repo create user2/hello --public --source=. --remote=origin

gh auth switch --user user1

this could apply all commands with auguments that involve full repo name. likegh repo clone github-user/repo-name
