* Create a timer pool

* The use of pool name is optional. Unique names are not required.
Currently, user needs to decide the timer resolution before creating a timer pool. But sometimes it will cause timer overrun as the system can't support such high resolution. So a new API is required to expose the timer capability to the user.
