Do not switch best connection on the controlled side too frequently due to the nomination from the controlling side.
We now use a single rule to determine connection switch on the controlled side. The rule is to select the new best connection based on the following order:
1. writable/receiving/connected state.
2. nominated
3. last time receiving data packet.
4. priority.
5. latency (rtt)
