Defines how jobs are moved in context.

Required methods

`fn remove_from_required(&self, ctx: &SolutionContext, job: &Job) -> bool`

Returns true if job is moved from required to ignored.

`fn promote_to_required(&self, ctx: &SolutionContext, job: &Job) -> bool`

Returns true if job is moved from ignored to required.

`fn remove_from_locked(&self, ctx: &SolutionContext, job: &Job) -> bool`

Returns true if job is removed from locked.

`fn promote_to_locked(&self, ctx: &SolutionContext, job: &Job) -> bool`

Returns true if job is moved to locked.
