NIFI-2459: HTTP Site-to-Site can't update remote peer topology if the
"bootstrap url" node is down
This PR migrates existing code which handles the situation, from
EndpointConnectionPool to PeerSelector, so that both RAW and HTTP transport
protocol has the same capability.
Added a unit test to confirm this scenario.
Also did an IT test using running NiFi cluster:
Used a 3 node cluster. Setup S2S specifying node 2 as the bootstrap node,
then stop node 2. Confirm data is sent to only node 1 and 3. Remote peer status
can still be refreshed. Then add Node 2 back, Confirm data is sent to node 1, 2
and 3.
