debug/error-gen: add option to generate errors at random percentage
Currently error-gen has a option where the percentage of the errors generated
can be specified. This patch adds a new option, which if given errors
are generated at random percentage. If both the random failure option and
the specific percentage of the errors are provided, then random error
generation is given preference.
