commit fb924933765238808feb05fb7178402058026897

Make server reconnect time a little bit more random

Add randomly up to 15 seconds to the reconnect delay for outgoing server
links when the connection has been "short" and therefore the "ConnectRetry"
delay is being enforced.

This should make it even more unlikely that two servers deadlock each
other when both are trying to connect to the other one at the same time,
for example in test environments.
