rpc: implement reconnect back-off strategy
When a connection failure happens, gluster tries to reconnect every 3
seconds. In some cases the failure is spurious, so a delay of 3 seconds
could be unnecessarily long.
This patch implements a back-off strategy that tries a reconnect as soon
as 1 tenth of a second. If this fails, the time is doubled until it's
around 3 seconds. After that, the reconnect is attempted every 3 seconds
as before.
