This should help improve load balancing when using TCP load balancer, where DNS will report a single IP and each connection made to that IP is pinned to a single backend instance.

This is one part of a solution for #59.

Along with #58, this should be the other half of the solution to resolve
#59.

This allows the leaf level transports to be periodically re-created.
That way, if by chance a single pool ends up in a state of limited
diversity (too many transports with persistent connections to the same
backend), re-creating the transport will allow it a chance to contact a
different backend, and thus be continually changing the mix of target
backends.
