cli: Do not print help on any failure

[cthulhu-rider]

Any error returned by implemented command executor leads to additional help output. It is useful when the user incorrectly formed a command, but not more.

Solution

Replace providing the RunE calls of to cobra.Command (errors of which are actually lead to help) with Run. With this approach command misprints are still handled, but other errors are written user friendly. For errors cmd.PrintErr function group, for logs - cmd.Print* w/o Err.
