This change aims to fix failures in the session factory load balancing tests that mock failure scenarios. For these tests, we randomly shut down ldap servers and bind a client socket to the port they were listening on. Unfortunately, we would occasionally encounter failures in these tests where a socket was already in use and/or the port we expected to connect to was wrong and in fact was to one of the ldap instances that should have been shut down. The failures are caused by the behavior of certain operating systems when it comes to binding ports and wildcard addresses. It is possible for a separate application to be bound to a wildcard address and still allow our code to bind to that port on a specific address. So when we close the server socket and open the client socket, we are still able to establish a connection since the other application is already listening on that port on a wildcard address. Another variant is that the os will allow a wildcard bind of a server socket when there is already an application listening on that port for a specific address. In order to do our best to prevent failures in these scenarios, this change does the following: 1. Binds a client socket to all addresses in an awaitBusy 2. Adds assumption that we could bind all valid addresses 3. In the case that we still establish a connection to an address that we should not be able to, try to bind and expect a failure of not being connected Closes #32190
