In case of full shutdown/startup and usage of dynamic ports it is
possible replicas get out of date address information.
Since they think there is enough replicas to form a quorum they will
not try to refetch address information immediately but after some delay.
This flag -using-dynamic-ports informs registry to wipe ports on startup
as empty ports are not considered valid addresses replicas will refetch
information quickly.
Note that in case of production rolling restart this is not a problem
as replica information changes slowly.
