CLI: Scheduler commands

[ohinckel]

Added two new scheduler commands to list scheduled tasks (but not logics, which are already listed by other commands):

• sl - list all tasks with a scheduled ordered by name
• st - list all tasks with a scheduled ordered by next execution time
• si - show information for given scheduler task

Example output for sl:

> sl
3 scheduler tasks:
Connections (scheduled for 2015-02-17 13:12:49+0100)
series (scheduled for 2015-02-17 13:12:49+0100)
sh.gc (scheduled for 2015-02-18 02:04:00+0100)
> 

Example output for st:

> st
3 scheduler tasks by time:
2015-02-17 13:33:29+0100 Connections
2015-02-17 13:33:29+0100 series
2015-02-18 02:04:00+0100 sh.gc
> 

Example output for si:

> si sh.gc
Task sh.gc {
  obj = <bound method SmartHome._maintenance of <__main__.SmartHome object at 0xe213b0>>
  prio = 8
  value = None
  next = 2015-03-23 02:04:00+01:00
  cron = {'4 2 * *': None}
  active = True
  cycle = None
}
