PR #1139 introduced a complexity that will have to be taken into account
as we figure out our release pipeline. This fix pins to cobrav1.0.0 as a
temporary workaround.
fixes: #1191
Issue Reference: https://github.com/spf13/cobra/issues/1056https://github.com/spf13/cobra/pull/922 introduced a new error
type that emitted when a command was not runnable. This caused
all commands w/o a run function set to error w/ that message and a status code of 1.
This change reverts the addition of that new error. Similar
functionality can be accomplished by leveraging RunE.
