Add an option to select pubsub service
When multiples pubsub services are available on a server, SàT chose the first it encounter. This choice is random and not reliable.
Some servers provides multiples pubsub services with the purpose to diversify ifs content (persistent data, volatile data, etc).
As a result, SàT may store blog comments, tickets, etc on pubsub services that are not intended for this purpose.
SàT should provide an option to let the user specify the pubsub service it should use.
