Add code to allocate server ports
Added code to find available server ports. Also added a trust manager that always trusts certificates. Made trust manager private so we can allocate new ones in the future, if we decide it isn't safe to re-use the same one over and over. Modified test code to allocate a port rather than assuming 8180 was not in use. Also modified retry parameters in other tests. Added another allocPort() that takes an IP address and then modified the other two to use that so the code does not have to be duplicated, while providing more functionality.
