Introduce builder-inspired way for configuring Nitrocli instance

In the future we would like to provide more ways for tests to create a
Nitrocli instance. In order to prevent explosion of with_XXX methods for
each possible combination of arguments, this change allows for an easier
configuration of an existing object with builder-pattern-inspired
modifier methods.
