更改调度器相关的 api

[felinae98]

当前形式的调度器

class ArknightsSchedConf(SchedulerConfig, name="arknights"):

    schedule_type = "interval"
    schedule_setting = {"seconds": 30}

class Arknights(NewMessage):

   ...
   scheduler_class = "arknights"

更改为

class ArknightsSchedConf(SchedulerConfig):

    schedule_type = "interval"
    schedule_setting = {"seconds": 30}
    name = "arknights"

class Arknights(NewMessage):

   ...
   scheduler = ArknightsSchedConf

新增 inline 调度器

class Arknights(NewMessage):

   ...
   scheduler = Schedule(schedule_type="interval", scheduler_setting={"seconds": 30})
