feat(cmd): add migrate flag to connect command

this is important for zero-input environments like docker and qri desktop, which need a surefire way to
get to a running qri node without interruption. callers that want no prompts at all should now use:

$ qri connect --setup --migrate

to auto-run setup when the qri repo path is empty, and auto run migrations before startup
