Fix some issues in sync package (#111)

Browse Source 
* Change default concurrent sync threads

* enhance log level in sync store

* Add rwlock in sync store to avoid concurrency issue

* enhance serial sync state machine log level

* wrap Instant for debug purpose

* add timestamp for connecting peers state

* Select random peer to sync chunks

* return sync peers states instead of connected peers only

* Use tokio async RwLock for sync store
