Missing RunSpecifiers in v6

[fpellet]

Hello,

I haven't seen a migration guide between versions 5 and 6.
Some RunSpecifier seems to have deleted:

• t.Every(1).Hours().At(option.Minute) => can be replaced with cron syntax
• t.Every(1).Months().OnTheLastDay().At(option.Hour, 0) => I haven't found an alternative, except to filter in the execute.

Could we add a method to specify the behavior directly if you no longer want to include this in the lib?
compute => this._calculator.PeriodCalculations.Add((Func<DateTime, DateTime>) (last => compute(last)))

We deliberately removed some functions to simplify the API and evaluate what features are truly useful in practice.

As a result, version 6.0.0 does not include an OnTheLastDay() method. The closest alternative is to schedule on a fixed day each month, for example:

run.Every(1).Months().On(28).At(option.Hour, 0)

Does this new version breaks something to you? Why would you need the OnTheLastDay()?

@tallesl What do you think of this custom schedule that @fpellet is suggesting? It seems useful to add such customization to the users, I dont know if it is hard to implement.

@fpellet you may refer to this #322

@jasonlaw Thank you for this suggestion for the first case. However, it becomes more complicated than cron syntax.
@VitorCioletti It's not quite the same thing; I need to run it on the last day of the month. So I'm going to filter on the execute. It's not insurmountable either. :)

Nevertheless, I think it would be a real plus to allow users to extend the API.
