Kir Kolyshkin ac038eab29 integration-cli: error report improvements 
1. After running d.Cmd(), in case an error is returned, it makes sense
to print command output, as its stderr may contain a clue about what
went wrong. This is by no means complete, just as far as I could go.

2. In case the comment in c.Assert is a constant string, it's better
to provide it as a comment which will be printed.

3. An arbitrary string should not be passed on to a function expecting
%-style formatting. Use %s to fix this.

4. Print the output string before transformation, not after.

5. Unify the output format (drop "out:" prefix").
