heatclient CLI doesn't raise errors

[Chmouel Boudjnah]

When there is a code error the heat CLI would just print the error but not properly raises an error which makes it hard for debugging when there is a code error.

Arguably this is more friendly and this should be the default but adding it to --debug is what the user would expect to see IMO (a traceback)

    Raise traceback on error when using CLI and -debug

    When --debug is specified to the CLI don't just print the simple error
    message but actually reraise that error.
