[PATCH 1/2] rteval: Support custom argument default value help

[Tomas Glozar <tglozar@redhat.com>]

Add an optional default_value option to sets returned from
ModuleParameters to specify a different default value help text than
the value of default field.

This is useful for cases where the default value depends on
the environment
