repoctl commands should be called by cobra commands

They should not BE cobra commands. Repoctl commands should verify
their own input, and they should directly access command line flags.
These should be passed on by the cobra command. This is important,
because repoctl commands might be called by other means.

Also, these commands might some day be put into a separate library.
