Code review comment for lp:~free.ekanayaka/landscape-client/config-failure

Thanks for the careful review, Sidnei.

I fixed all the lints but two, as they are due to comments preceding function definitions.

Good point, I moved exit_with_error at the beginning of the main function.

[2]

Right, that's not an issue because we're not running that code inside a callback.
