CLI command for un-/retire schedules

[Walter.Koller]

We are preparing our BP upgrade and for this period of time we want to stop all schedules.

There is no 'disable' (ie temporarily prevent schedules from running) schedule feature but un-/retire only. Retired schedules are a mixture of outdated schedules that might not yet be possible to delete or are kept for other reasons. There is also now was to structure schedules in groups/folders so it may also be the case that some infrequently used schedules are retired just better manage regularly executed schedules. 

So the idea was to create scripts based on currently active schedules to bulk un-/retire them and also making sure the exact same schedules that have been active are unretired again, without having to keep manual separate lists and have to visually check against those lists

Unfortunately there is only /startschedule and /deleteschedule parameter for automateC but there is no un-/retire parameter. So it would be great to also have /retireschedule and /unretireschedule (and also /stopschedule since this is now supported in BP UI). Setting expiration dates would also be helpful
