#3838: Many tests still invoke the logic to automatically assign a port number to
the main tub

---------------------+---------------------------
 The default behavior for starting a client without `[node]tub.port`
 configured is to try to automatically allocate a tcp port.

 This logic is failure prone because it's not actually possible to reliably
 allocate a tcp port that will be unused at some future point.

 Many tests still trigger this behavior by creating nodes without this
 configuration item.  As a result, test suite runs often include a spurious
 failure.
