LiveSession: check bandwidth in 10s interval to support adaptive stream switch

schedule another check bandwidth event when previous bandwidth check event responds.
so that HLS will realize adaptive stream switch when network bandwidh change.

the bug exists in kitkat 4.4.2, brough by AOSP upgrade and it will impact HLS
bandwidth switch feature

Steps to reproduce:
 1. connect phone /tablet to wifi, adjust router to set initial wifi bandwidth to low bandwidth
 2. lauch browser to access http live streaming server and start playback on full screen (there're three TS streaming for 900kbps/300kbps/100kbps bandwidth)
 3. During playing streaming, change network bandwidth to be high,such as 1000kbps

expected result: streaming switches to high quality
actual result: streaming does not switch to high quality
