To config TaskManager's default behavior. TaskManager Config is optional.
用于配置TaskManager的一些默认配置。若不配置，TM将采用内部默认设置。

TaskManager.config()
                .setDefaultTimeOut(3000)
                .setLogTracker(host ? TMTracker.get() : null)
                .enableMemoryCleanUp(true)
                .enableObjectReuse(true)
                .enableFullLog(false)
                .setWaitTimeCollectThreshold(500)
                .initTaskManager(application);

public TaskManagerConfig setDefaultTimeOut(int timeOut)
To set default blocking time for API "TM.needTaskSync".
用于设置任务的默认等待时间。

public TaskManagerConfig setLogTracker(ITracker tracker)
ITracker is an interface for TM debug system. If a tracker has been set , you can enable debug crash checking , critical log out put etc...
ITracker 是TM的调试接口。设置Tracker后，可以开启debug crash 以暴露验严重务逻辑问题，输出关键日志等等。

public TaskManagerConfig enableObjectReuse(boolean enable) new feature added in 1.3.5.
If object reuse is enabled , some of TM's object will be resued.

public boolean isFullLogEnabled(boolean enable)
If enabled, full log will be output to ITracker.

public TaskManagerConfig setWaitTimeCollectThreshold(int time)
If any statement is waiting for a task to finish for more than threshold time, the waiting stack trace will be printed to ITracker.
当等待任务完成的时间超出设定的阈值，代码阻塞位置的堆栈信息将会被打印到ITracker。

public TaskManagerConfig setLowTaskPriorityTaskMaxWaitTime(int timeInms)
TM has supported dynamic task priority. It a task has been waiting for too long , the task priority will be changed, so that it can gain cpu time.
TM 支持了动态优先级，任务的优先级将随着等待时间的增加而升高。从而保证低优先级的任务也能得到CPU时间。

🌟 New API 1.3.7
public TaskManagerConfig setThreadPoolStrategy(int strategy) Added in 1.3.7. By default, new thread pool is used for TM tasks to provide a bettter performance. You may call setThreadPoolStrategy(ITaskManagerConfig.STRATEGY_POOL_EXECUTOR) to switch back to the former thread pool.
默认使用新的线程池。新线程池的可靠性正在验证中。可通过此方法切换到旧的线程池。

public void initTaskManager(Application application)
Config TaskManager.
