Combine Schedule Timing and Schedule Unit in to a single attribute

[eoyilmaz]

User Story

As the developer of Stalker I want to combine ScheduleMixin.schedule_timing and ScheduleMixin.schedule_unit into a single attribute which might be called a ScheduleInfo that combines the schedule related data and logic into one class, so that it is easiear to maintain schedule realated code.

Acceptance Criteria

• Create a new class called ScheduleInfo.
• Add attributes like timing, unit, model, constraint.
• Move ScheduleMixin methods and properties like schedule_seconds (rename to seconds), to_unit(), to_seconds(), least_meaningful_time_unit() to this class.
• Allow it to understand string values like "10h", "1h5m" etc.
